Description

Technical Field

[0001] The technical field of the invention is methods for assessing the near vision accommodation status of non-presbyopic individuals.

[0002] The present invention relates to a method for assessing the near vision accommodation state of a non-presbyopic individual, and in particular to a method for automatically assessing the near vision accommodation state of a non-presbyopic individual. The present invention also relates to an apparatus, a computer program product and a recording medium. Background Art

[0003] To date, due to lack of time and / or practice, near vision examinations have been performed almost exclusively on presbyopic subjects, that is, subjects over 40 years of age whose accommodative status has deteriorated with age and who require near vision correction.

[0004] However, young subjects often suffer from over- or under-accommodation problems. Because these problems affect distance vision, these young subjects are often misdiagnosed, which often leads to poor management of their distance vision when their near vision could be managed, thereby avoiding exacerbation of their distance and near vision disorders.

[0005] Near vision examinations include, among other things, an assessment of the subject's accommodation state, and in particular the flexibility of the accommodation / convergence relationship. Two types of abilities are usually tested: motor ability, requiring the subject to initiate gradual changes in accommodation (0.25 diopter steps) on a fixed plane of convergence; and step ability, requiring the subject to initiate instantaneous accommodation on the same fixed plane of convergence with a step length greater than 0.25 diopters, and usually with 2.00 diopters.

[0006] In near vision testing, the NRA / PRA test for negative relative amplitude and positive relative amplitude is one of the tests used by health professionals to evaluate the motor ability of presbyopic or non-presbyopic individuals.

[0007] The test consists of placing a text corresponding to a visual acuity of 80% of the subject's maximum near visual acuity at a given distance that differs depending on whether the subject is presbyopic or non-presbyopic, and advancing the convex lens in steps of +0.25 diopters until the subject perceives a first constant blur (RNA), and then advancing the concave lens in steps of -0.25 diopters until the subject perceives a first constant blur (PRA). The required downlighting in presbyopic subjects, or the flexibility of the accommodation / convergence relationship in non-presbyopic subjects, can then be assessed, and more generally indications given for possible management for the latter (downlighting, visual training, distance vision reassessment, etc.).

[0008] RNA / PRA testing is performed manually by practitioners and is therefore relatively time consuming, which is incompatible with the management of an increasing number of patients.

[0009] For these reasons, for non-presbyopes, practitioners more often prefer an accommodative reading test (Accommodative Rock Chart), which consists of alternately placing a convex lens with a value of +2.00 diopters and then a concave lens with a value of -2.00 diopters in front of the subject's eyes. As soon as the subject can clearly and simply see a text placed 40 cm from his or her eyes corresponding to a visual acuity of 80% of his or her maximum acuity, the switch from one lens to the other is made. The number of cycles performed in one minute then allows the individual's stage ability to be assessed.

[0010] Although quicker than the NRA / PRA test, the accommodative reading test does not give any information about the motor ability of the individual and does not allow for an assessment of the possible near vision correction that the subject will require.

[0011] Therefore, there is a need to provide a test that allows the assessment of a young subject's regulatory state, ie his or her motor and phasic abilities, which is fast, reliable and automatic. Summary of the invention

[0012] The present invention provides a solution to the above problems by allowing automatic assessment of the motor and phase abilities of non-presbyopic subjects.

[0013] A first aspect of the present invention relates to a method for automatically assessing the near vision accommodation state of a non-presbyopic individual, the method being implemented and performed by a computer after an assessment of the individual's distance vision has resulted in the preparation of a distance vision assessment report, the method comprising the following steps performed in sequence:

[0014] - placing at least one opthalmology font at a fixed distance from the individual's eye:

[0015] o If the individual fails to read the trial vision font, the method is interrupted and a near vision assessment report is generated including a first initial recommendation;

[0016] - An initial convex lens having a value in the range [+0.50; +1.00] diopters is placed in front of the individual's eye:

[0017] o If the individual prefers to have no initial lens rather than with the initial lens, the method is interrupted and a near vision assessment report is generated that includes a second initial recommendation;

[0018] ○ If the individual can see no difference with or without the initial lens, remove the initial lens:

[0019] If, after removal of the initial lens, the individual has adaptation time to see clearly again, then place the initial lens;

[0020] Otherwise:

[0021] ■If the distance vision assessment report does not recommend a near vision assessment, the method is interrupted and a near vision assessment report is generated;

[0022] ■Otherwise, place the initial lens;

[0023] - placing a first convex lens having a value in the range of [+0.50; +1.00] diopters in front of the individual's eye:

[0024] o if, after placement of the first lens, the individual has blurred vision, interrupting the method and generating a near vision assessment report including a first recommendation;

[0025] - placing a second convex lens having a value in the range of [+0.50; +1.00] diopters in front of the individual's eye:

[0026] o if, after placement of the second lens, the individual has blurred vision, interrupting the method and generating a near vision assessment report including the first recommendation;

[0027] - placing a third convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye:

[0028] o if, after placement of the third lens, the individual has blurred vision, interrupting the method and generating a near vision assessment report including a first recommendation;

[0029] - placing a fourth convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye:

[0030] ○ If after placement of the fourth lens, the individual has blurred vision, and:

[0031] If the distance vision assessment report does not recommend a near vision assessment, the method is interrupted and a near vision assessment report is generated;

[0032] = Otherwise, the method is interrupted and a near vision assessment report including a second suggestion is generated;

[0033] - placing a fifth convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye:

[0034] ○ If after placement of the fifth convex lens, the individual has blurred vision, and:

[0035] If the distance vision assessment report does not recommend a near vision assessment, the method is interrupted and a near vision assessment report is generated;

[0036] = Otherwise, the method is interrupted and a near vision assessment report including the third suggestion is generated;

[0037] - placing a sixth convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye:

[0038] ○ If after placement of the sixth lens, the individual has blurred vision, and:

[0039] If the distance vision assessment report does not recommend a near vision assessment, the method is interrupted and a near vision assessment report is generated;

[0040] = Otherwise, the method is interrupted and a near vision assessment report including the third suggestion is generated;

[0041] Otherwise:

[0042] ● Remove the initial lens and the first, second, third, fourth, fifth and sixth lenses;

[0043] ● A first final convex lens with an intermediate correction is placed in front of the individual's eye, and then the first final lens is removed and a second final convex lens with a strong correction is placed in front of the individual's eye:

[0044] ■ if the individual prefers the first final lens over the second final lens, or if the individual can see no difference between the first final lens and the second final lens, generating a near vision assessment report including a fourth recommendation;

[0045] ● Otherwise, generate a near vision assessment report including the fifth recommendation.

[0046] By means of the present invention, the practitioner can assess the accommodative state, i.e. both motor and phasic abilities, of young subjects by performing an alternative to the RNA / PRA test adapted for non-presbyopic subjects and optimized in time. On the one hand, the method according to the first aspect of the invention saves the advancement of the concave lens, since, in the case of automated testing and in situations where information is to be collected, advancing the concave lens does not provide an additional element to the conclusion obtained by advancing the convex lens. In fact, a normal to high PRA gives little indication other than the fact that the subject has good accommodation and divergence. A low PRA is almost always synonymous with the need for a lower addition of light, which is already defined by the RNA measurement and is associated with convergence problems that can only be confirmed by other tests if necessary. On the other hand, young subjects usually have no problem with de-accommodation of a convex lens below 1.50 diopters. Therefore, the method according to the first aspect of the invention advances the first convex lens in steps within the range of [0.50 and 1.00] diopters, rather than in steps of 0.25 diopters, so that the time spent on implementing the method can be reduced, and in addition to the movement ability evaluated by advancing the lens, the stage ability can be evaluated by a larger correction difference between each lens (step size greater than 0.25 diopters). In addition, the test is fully automatic, i.e. it does not require the intervention of the practitioner. Therefore, this evaluation is non-restrictive and is a diagnostic aid for the practitioner.

[0047] In addition to the features discussed immediately above in the paragraph above, the method according to the first aspect of the invention may have one or more of the following additional features, considered alone or in any technically possible combination.

[0048] According to an alternative embodiment, the first initial suggestion is to consult an ophthalmologist and / or to perform a near vision assessment on trial glasses.

[0061] Thus, the method according to the first aspect of the invention can be implemented by an individual who is assessing his or her regulatory state. In practice, the individual himself or herself selects the selection suggestions and / or symbols displayed on the display device via the selection device, and the processing device takes these selections into account to sequence the steps of the method.

[0062] A third aspect of the invention relates to a computer program product comprising software instructions which, when the program is executed by a computer, implement the method according to the first aspect of the invention.

[0063] A fourth aspect of the present invention relates to a computer-readable recording medium on which a computer program product according to the third aspect of the present invention is recorded.

[0067] Figure 2 A schematic diagram is shown of an embodiment of an apparatus according to the second aspect of the invention. DETAILED DESCRIPTION

[0068] Unless otherwise specified, identical elements appearing in different figures have unique reference numerals.

[0069] A first aspect of the invention relates to a method for assessing the near vision accommodation state of a non-presbyopic individual.

[0070] By "accommodation" is meant the focusing of vision, in particular by means of a variation of the curvature of the lens as a function of the distance of an object, so as to form a sharp image on the retina.

[0071] By "near vision accommodation state of an individual" is meant the near vision accommodation behavior of that individual.

[0072] By "non-presbyopic individual" is meant an individual under the age of 40 years.

[0073] The method according to the first aspect of the invention is automatic, ie it is computer-implemented. In particular, its implementation does not require intervention by a practitioner.

[0074] After the individual's distance vision is assessed, the method according to the first aspect of the invention is performed. At the end of this assessment, a distance vision assessment report is prepared. The report may or may not recommend a near vision assessment for the individual. Even if the distance vision assessment report does not recommend a near vision assessment, the practitioner may still choose to assess near vision.

[0075] For example, the distance vision evaluation report may suggest near vision when the individual has near vision disease and / or when the individual has accommodative spasticity during the distance vision evaluation and / or when the distance vision evaluation reveals abnormal accommodative behavior.

[0076] Figure 1 is a block diagram showing the sequence of steps 101 to 120 of the method 100 according to the first aspect of the present invention.

[0077] A first step 101 of method 100 comprises placing at least one opthalmology font at a fixed distance from an individual's eye.

[0078] By "eye test fonts" is meant characters or graphics used to measure visual acuity.

[0079] For example, a first step 101 comprises placing at least one set of letters corresponding to a minimum acuity of 4 / 10 in front of the eyes of the individual.

[0080] For example, the sight test font is placed 40 cm from the individual's eyes.

[0081] If the first condition C1 is met, ie if the individual fails to read the trial sight font, the second step 102 of the method 100 is performed.

[0082] A second step 102 of the method 100 includes interrupting the method 100 and generating a near vision assessment report including a first initial recommendation.

[0083] For example, a first initial recommendation is to consult an ophthalmologist and / or perform a near vision assessment on trial glasses.

[0084] If the first condition C1 is not satisfied, the third step 103 of the method 100 is executed.

[0085] The third step 103 of the method 100 comprises placing an initial convex lens having a value within a closed range of [+0.50; +1.00] diopters in front of the individual's eye.The initial lens is then placed between the individual's eye and a trial eye font.

[0086] If the second condition C2 is met, ie if the individual prefers to be without an initial lens rather than with an initial lens, the fourth step 104 of the method 100 is performed.

[0087] By "the individual prefers to be without the initial lens rather than with the initial lens" it is meant that the individual experiences less discomfort associated with his or her vision without the initial lens than with the initial lens (more comfortable vision without the initial lens).

[0088] A fourth step 104 of the method 100 includes interrupting the method 100 and generating a near vision assessment report including a second initial recommendation.

[0089] For example, the second initial suggestion is to perform accommodation training exercises and / or to perform a binocular vision assessment.

[0090] If the second condition C2 is not satisfied, and the third condition C3 is satisfied, the fifth step 105 of the method 100 is performed.

[0091] If the individual can see no difference with or without the initial lens, the third condition C3 is met.

[0092] A fifth step 105 of method 100 includes removing the initial lens.

[0093] If the fourth condition C4 is met, ie if after removal of the initial lens the individual has an adaptation time to see clearly again, a sixth step 106 of the method 100 is performed.

[0094] A sixth step 106 of method 100 includes repositioning the initial lens.

[0095] The sixth step 106 of the method 100 is followed by an eighth step 108 of the method 100 .

[0096] If the fourth condition C4 is not satisfied, and the fifth condition C5 is satisfied, the seventh step 107 of the method 100 is performed.

[0097] If the distance vision assessment report does not recommend a near vision assessment, the fifth condition C5 is met.

[0098] A seventh step 107 of method 100 includes interrupting method 100 and generating a near vision assessment report.

[0099] If the fourth condition C4 is not satisfied and the fifth condition C5 is not satisfied, the sixth step 106 of the method 100 is performed.

[0100] An eighth step 108 of method 100 includes placing a first convex lens having a value within a closed range of [+0.50; +1.00] diopters in front of the individual's eye.

[0101] If the sixth condition C6 is met, ie if after placement of the first lens the individual has blurred vision, a ninth step 109 of the method 100 is performed.

[0102] A ninth step 109 of method 100 includes interrupting method 100 and generating a near vision assessment report including a first recommendation.

[0103] For example, the first recommendation is to perform conditioning training exercises.

[0104] If the sixth condition C6 is not satisfied, the tenth step 110 of the method 100 is executed.

[0105] A tenth step 110 of method 100 includes placing a second convex lens having a value within a closed range of [+0.50; +1.00] diopters in front of the individual's eye.

[0106] If the seventh condition C7 is met, ie if after placement of the second lens the individual has blurred vision, a ninth step 109 of the method 100 is performed.

[0107] If the seventh condition C7 is not satisfied, the eleventh step 111 of the method 100 is executed.

[0108] An eleventh step 111 of method 100 includes placing a third convex lens having a value within a closed range of [+0.25; +0.50] diopters in front of the individual's eye.

[0109] If the eighth condition C8 is met, ie if after placement of the third lens the individual has blurred vision, a ninth step 109 of the method 100 is performed.

[0110] If the eighth condition C8 is not satisfied, the twelfth step 112 of the method 100 is executed.

[0111] A twelfth step 112 of method 100 includes placing a fourth convex lens having a value within a closed range of [+0.25; +0.50] diopters in front of the individual's eye.

[0112] If the ninth condition C9 is met, ie if after placement of the fourth lens the individual has blurred vision, and if the fifth condition C5 is met, the seventh step 107 of the method 100 is performed.

[0113] If the ninth condition C9 is satisfied, and the fifth condition C5 is not satisfied, the thirteenth step 113 of the method 100 is executed.

[0114] A thirteenth step 113 of method 100 includes interrupting method 100 and generating a near vision assessment report including a second recommendation.

[0115] For example, a second recommendation is to perform a binocular vision assessment.

[0116] If the ninth condition C9 is not satisfied, the fourteenth step 114 of the method 100 is executed.

[0117] A fourteenth step 114 of method 100 includes placing a fifth convex lens having a value within a closed range of [+0.25; +0.50] diopters in front of the individual's eye.

[0118] If the tenth condition C10 is met, ie if after placement of the fifth lens the individual has blurred vision, and if the fifth condition C5 is met, the seventh step 107 of the method 100 is performed.

[0119] If the tenth condition C10 is satisfied, and the fifth condition C5 is not satisfied, the fifteenth step 115 of the method 100 is executed.

[0120] A fifteenth step 115 of method 100 includes interrupting method 100 and generating a near vision assessment report including a third recommendation.

[0121] For example, the third suggestion is to suggest a lower light addition with a weak correction value, for example, the weak correction is 0.50 diopters.

[0122] If the tenth condition C10 is not satisfied, the sixteenth step 116 of the method 100 is executed.

[0123] A sixteenth step 116 of method 100 includes placing a sixth convex lens having a value within a closed range of [+0.25; +0.50] diopters in front of the individual's eye.

[0124] The value of the initial lens and the value of each of the first, second, third, fourth, fifth and sixth lenses are selected so that the sum of the values ​​of these lenses is equal to the inverse of the fixed distance in meters between the individual's eye and the trial font.

[0125] Thus, for a fixed distance of 40 cm, the sum of the value of the initial lens and the values ​​of the first, second, third, fourth, fifth and sixth lenses equals +2.50 diopters.

[0126] If an eleventh condition C11 is met, ie if after placement of the sixth lens the individual has blurred vision, and if the fifth condition C5 is met, the seventh step 107 of the method 100 is performed.

[0127] If the eleventh condition C11 is satisfied, and the fifth condition C5 is not satisfied, the fifteenth step 115 of the method 100 is executed.

[0128] If the eleventh condition C11 is not satisfied, the seventeenth step 117 of the method 100 is executed, followed by the eighteenth step 118 of the method 100 .

[0129] A seventeenth step 117 of method 100 includes removing the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens from the front of the individual's eye.

[0130] An eighteenth step 118 of method 100 includes placing a first final convex lens having an intermediate correction in front of the individual's eye, then removing the first final lens and placing a second final convex lens having a strong correction in front of the individual's eye.

[0131] Correction values ​​for the intermediate correction correspond to correction values ​​that are strictly lower than the strong correction, and correction values ​​for the weak correction correspond to correction values ​​that are strictly lower than the intermediate correction.

[0132] The intermediate correction and the strong correction may be selected from the following values: +0.50 diopters; +0.75 diopters; +1.00 diopters; +1.25 diopters.

[0133] If the twelfth condition C12 is met, ie if the individual prefers the first final lens to the second final lens, or if the individual can see no difference between the first final lens and the second final lens, the nineteenth step 119 of the method 100 is performed.

[0134] By "the individual prefers the first final lens to the second final lens" it is meant that the individual experiences less discomfort related to his or her vision using the first final lens than using the second final lens (more comfortable vision using the first final lens).

[0135] A nineteenth step 119 of method 100 includes generating a near vision assessment report including the fourth recommendation.

[0136] For example, the fourth suggestion is to add light to the intermediate correction values.

[0137] If the twelfth condition C12 is not satisfied, the twentieth step 120 of the method 100 is executed.

[0138] A twentieth step 120 of method 100 includes generating an assessment report including the fifth recommendation.

[0139] For example, the fifth suggestion is to suggest a lower light addition with a strong correction value.

[0140] Throughout the method 100, the individual selects between several options in order to verify or not verify a condition. For example, the individual must select between the option "I can see the trial vision font" and the option "I cannot see the trial vision font" to verify or not verify the first condition C1. The selection may be made by the individual himself or herself via a selection device, or by a practitioner, or by any other person who inputs the individual's selection, for example, in a console or computer.

[0141] At the end of the method 100 according to the first aspect of the invention, a near vision assessment report is generated, comprising a conclusion and possibly one of the previously mentioned recommendations.

[0142] The near vision assessment report may also include additional recommendations depending on, for example, the individual's distance vision assessment report.

[0143] The practitioner can then use this near vision assessment report to suggest a solution that is appropriate for the individual. The practitioner can choose whether to follow one or more of the recommendations suggested in the near vision assessment report.

[0144] For young presbyopes, i.e. subjects from 40 to 44 years old (inclusive), alternatives to the method 100 according to the first aspect of the invention may be suggested. Thus, if after the third step 103 of the method 100, the individual prefers the initial lens, or if after the fifth step 105 of the method 100, the fourth condition C4 is satisfied, or if after the fifth step 105 of the method 100, the fourth condition C4 and the fifth condition C5 are not satisfied, the eighteenth step 118 of the method 100 is performed.

[0145] A second aspect of the invention relates to an apparatus for assessing the near vision accommodation state of a non-presbyopic individual.

[0146] Figure 2 A schematic diagram of an apparatus 200 according to the second aspect of the invention is shown.

[0147] The device 200 according to the second aspect of the invention comprises a memory 203 and a calculator 204 comprising means configured to perform the steps of the method 100 according to the first aspect of the invention.

[0148] The apparatus 200 also includes a placement device 202 configured to place the optical lens in front of an eye of an individual.

[0149] For example, the placement device 202 is an automatic refractor head.

[0150] The apparatus 200 further comprises a display device 201 configured for displaying at least one opthalmological font at a fixed distance from the eyes of the individual.

[0151] For example, the display device 201 is a screen or a poster.

[0152] According to the first embodiment, the display device 201 is further configured to display a verification suggestion and / or symbol.

[0153] For example, the display device 201 is configured to display a symbol that verifies that one lens is superior to another lens.

[0154] The device 200 then further comprises selection means 206 configured to select suggestions and / or symbols, and more precisely to allow the user to select suggestions and / or symbols, and processing means 205 configured to process the user selection.

[0155] For example, the selection device is a remote control, a tablet, a console or a microphone.

[0156] For example, the processing device 205 is a calculator. For example, the processing device 205 is included in the calculator 204.

[0157] For example, after the third step 103 of the method 100, the display device 201 displays a first symbol for selecting an initial lens, a second symbol for selecting without an initial lens, and a third symbol for indicating that there is no difference with or without the initial lens. The individual selects the third symbol by means of the selection device 206, and the processing device 205 processes the selection of the third symbol to initiate the execution of the fifth step 105 of the method 100.

A method (100) for automatically assessing the near vision accommodation state of a non-presbyopic individual, the method (100) being performed after an assessment of the distance vision of the individual has resulted in the preparation of a distance vision assessment report, characterized in that The method comprises the following steps performed in sequence: - placing at least one eye test font at a fixed distance from the individual's eye (101): o If the individual fails to read the trial vision font (C1), the method (100) is interrupted and a near vision assessment report (102) is generated including a first initial recommendation; - Placing an initial convex lens having a value in the range [+0.50; +1.00] diopters in front of the individual's eye (103): o If the individual prefers to have no initial lens rather than have the initial lens (C2), the method (100) is interrupted and a near vision assessment report (104) is generated including a second initial recommendation; o If the individual can see no difference with or without the initial lens (C3), then remove the initial lens (105): If, after removal of the initial lens, the individual has an adaptation time to see clearly again (C4), then the initial lens is placed (106); ·otherwise: ■ If the distance vision assessment report does not recommend a near vision assessment (C5), the method is interrupted (100) and a near vision assessment report is generated (107); ■ Otherwise, place the initial lens (106); - placing a first convex lens having a value in the range of [+0.50; +1.00] diopters in front of the individual's eye (108): o If, after placement of the first lens, the individual has blurred vision (C6), the method (100) is interrupted and a near vision assessment report (109) is generated that includes a first recommendation; - placing a second convex lens having a value in the range of [+0.50; +1.00] diopters in front of the individual's eye: o if, after placement of the second lens, the individual has blurred vision (C7), interrupting the method (100) and generating a near vision assessment report (109) including a first recommendation; - placing a third convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye (111): o if, after placement of the third lens, the individual has blurred vision (C8), interrupting the method (100) and generating a near vision assessment report (109) including a first recommendation; - placing a fourth convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye (112): o If after placement of the fourth lens, the individual has blurred vision (C9), and: If the distance vision assessment report does not recommend a near vision assessment (C5), the method (100) is interrupted and a near vision assessment report (107) is generated; Otherwise, the method (100) is terminated and a near vision assessment report (113) is generated including a second suggestion; - placing a fifth convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye (114): o If after placement of the fifth convex lens, the individual has blurred vision (C10), and: If the distance vision assessment report does not recommend a near vision assessment (C5), the method (100) is interrupted and a near vision assessment report (107) is generated; Otherwise, the method (100) is terminated and a near vision assessment report (115) including a third suggestion is generated; - placing a sixth convex lens having a value in the range of [+0.25; +0.50] diopters in front of the individual's eye (116): o If after placement of the sixth lens, the individual has blurred vision (C11), and: If the distance vision assessment report does not recommend a near vision assessment (C5), the method (100) is interrupted and a near vision assessment report (107) is generated; Otherwise, the method (100) is terminated and a near vision assessment report (115) including a third suggestion is generated; Otherwise: Removing the initial lens and the first, second, third, fourth, fifth and sixth lenses (117); • Placing a first final convex lens with an intermediate correction in front of the individual's eye, and then removing the first final lens and placing a second final convex lens with a strong correction in front of the individual's eye (118): ■ if the individual prefers the first final lens over the second final lens, or if the individual can see no difference between the first final lens and the second final lens (C12), generating a near vision assessment report (119) including a fourth recommendation; ■ Otherwise, generate a near vision assessment report (120) including the fifth recommendation.

2. The method (100) according to claim 1, characterized in that: The first initial recommendation is to consult an ophthalmologist and / or have a near vision assessment performed on trial spectacles.

3. The method (100) according to claim 1, characterized in that: The second initial suggestion is to perform accommodation training exercises and / or to perform a binocular vision assessment.

4. The method (100) according to claim 1, characterized in that: The first suggestion is to perform conditioning training exercises.

5. The method (100) according to claim 1, characterized in that: The second suggestion is to perform a binocular vision assessment.

6. The method (100) according to claim 1, characterized in that: The third suggestion is to suggest a lower addition light with a weak correction value.

7. The method (100) according to claim 1, characterized in that: The fourth suggestion is to suggest a lower addition light with an intermediate correction value.

8. The method (100) according to claim 1, characterized in that: The fifth suggestion is to suggest a lower addition of light with a strong correction value.

9.
