Problems solved by technology

However, in daily life and work, patients not only have the need to look far away, especially now that electronic equipment is becoming more and more developed and the penetration rate is getting higher and higher, resulting in a greatly increased time for people to see near, even exceeding the need for looking far away
If you wear far-sighted glasses to see near for a long time, the eye muscles will be overloaded, which will eventually lead to eye fatigue and deepening of myopia.
At the same time, glasses that can only see far and clearly cannot guarantee whether the peripheral vision will be distorted or whether the vision feedback is normal during exercise, etc.
Therefore, the traditional optometry method is only suitable for determining the objective diopter of patients, but there are great defects in prescription glasses

Embodiment

[0018] Embodiment: scene simulation optometry (see attached figure 1 ), including steps: S01: wear corrective glasses; S02: fixate on the distance target; S03: adjust the power and record until the distance target is clear; S04: quickly switch to fix the near target; S05: adjust the power and record , until the focus on the distance target is switched to the near target, the near target of 1.0 is clear; S06: get the test result.

[0019] The scene simulation optometry method of this embodiment also includes eye test for standard screen brightness at close range, eye peripheral vision test, and eye test for motion state.

[0020] Eye test for standard screen brightness at close range (such as figure 2 ) includes steps: the subject wears corrective glasses with clear vision; take a luminous screen with standard brightness, place it at a distance from the electronic equipment used by the subject in daily life, and let the subject look at the near vision chart 1.0 in the screen...

Abstract

The invention discloses a scene simulation optometric method which is characterized by comprising the following steps: enabling a patient to wear correction glasses and look at far sighting marks; adjusting and recording the power until the far sighting marks are clear; enabling the patient to quickly switch to look at near sighting marks; adjusting and recording the power until the 1.0 near sighting marks are clear when the patient switches from the far sighting marks to the near sighting marks; obtaining the test result. The common eye using demand states of the patient in daily life are simulated through scene simulation, then the power of the worn glasses is adjusted according to the practical situation of each state, the optometric method pays attention to advancing with the times, the targeted testing is carried out according to the practical eye using environment in the modern life.

Description

technical field [0001] The invention relates to optometry technology for wearing glasses, in particular to a scene simulation optometry method. Background technique [0002] Optometry is a process of qualitative and quantitative inspection, experimentation and analysis made by optometrists on the premise of excluding the influence of pathological factors on the vision and visual function of the eye. Equipped with a pair of comfortable glasses to obtain clear vision is the pain and expectation of every person with refractive errors. However, often due to the influence and limitation of various factors, the same patient has different results when optometry is performed at different times, conditions, instruments, and environments. [0003] There are many traditional diopter detection methods, but there are certain errors in the accuracy. The appearance of this error is often caused by the simple optometry method. [0004] The important reason is that the traditional optome...
