Description

Technical Field

[0001] The utility model belongs to the technical field of lenses, and in particular relates to a reverse microstructure array optical lens for teenagers. Background Art

[0002] What is hyperopia reserve? In simple terms, hyperopia reserve is the reserve of eye adjustment ability, which is generally used for children. From a professional point of view: Hyperopia reserve: Hyperopia before emmetropization is mostly physiological hyperopia, which is a kind of "hyperopia reserve", which can be understood as a "buffer zone" to "counter" the development of myopia. Insufficient hyperopia reserve means that the naked eye vision is normal. Although the refractive state after mydriasis optometry does not reach the myopia standard, the hyperopia degree is lower than the physiological value range of the corresponding age group. For example, if the physiological refractive power of children aged 4 to 5 years old is 150 to 200 degrees of hyperopia, there is a hyperopia reserve of 150 to 200 degrees. If the physiological refractive power of children in this age group is only 50 degrees of hyperopia, it means that their hyperopia reserve is consumed too much and myopia may occur earlier.

[0003] The dangers of too high hyperopia reserve: When the degree of hyperopia is too high, accommodation cannot compensate, resulting in amblyopia in children; when the degree of hyperopia is too high, excessive use of accommodation can easily cause eye discomfort and fatigue; excessive use of accommodation may also cause increased convergence of the two eyes, causing esotropia, which is called refractive accommodation esotropia.

[0004] Reducing excessive hyperopia reserve can be achieved through intervention with optical lenses, but there are currently no special lenses on the market that are specifically designed to reduce excessive hyperopia reserve. Utility Model Content

[0005] In view of this, the technical problem to be solved by the utility model is to provide a reverse microstructure array optical lens for teenagers, which solves the problem of the lack of lenses for reducing excessive hyperopia reserve in the prior art.

[0007] Furthermore, the long axis of the above-mentioned single-focus visual area is oriented in the horizontal direction.

[0008] Furthermore, the upper and lower sides of the above-mentioned microstructure defocusing area are parallel, and the left and right sides are parallel, and the length of the upper and lower sides is longer than the length of the left and right sides.

[0009] Furthermore, the reverse defocus amount of the above-mentioned lens is -4.0D.

[0010] Furthermore, the reverse defocus amount of the above-mentioned microlens is -4.5D.
