Based on looking far, the additional positive degree required by the discountglasses lens can play a role in adjusting the eye position. For individuals with implicit bias, it is mainly due to the use of eye concentration and regulation when approaching, which causes regulatory fatigue.

The inward rotation of the eyeball is large, and more negative fusion imaging functions are needed to correct the deviation of the eyeball. However, if the fusion imaging function is not large enough, it can cause visual fatigue and even become strabismus. This can reduce the use of adjustment when the eyes are closed, help your eyes adjust, and thus reduce the generation of regulatory sets, reducing the inward rotation of the eyeball.

For children with abnormal visual function, when the adjustment lag is large, working at close range will cause the imaging focus to move backward, resulting in hyperopia defocusing. This will stimulate the backward growth of the eye axis, thereby deepening myopia.

Based on looking far, the additional positive degree required by the children's eyeglasses lens can reduce the regulatory stimulation on the eyes. When the stimulation is reduced, the corresponding regulatory lag will also decrease, which has a certain control effect on the growth of myopia.

Adjusting lag, for example, is when the brain asks your eyes to use it without fully cooperating, and that part of the lazy force is called adjusting lag.

What kind of cheapest eyeglasses lenses can increase the degree adjustment? There are mainly progressive multifocal lenses, dual beam lenses, triple beam lenses, and fatigue-resistant lenses, among which the structure of fatigue-resistant lenses is similar to that of progressive multifocal lenses.
