Embodiment Construction

[0017] Because people with social anxiety disorder are afraid of facing crowds, the most direct way is to narrow their effective field of vision and relieve tension. A straightforward way to reduce the wearer's effective field of view is to see a blurred image through the surrounding area, which can be accomplished in a number of ways.

[0018] In order to achieve the above purpose, it can be achieved by changing the optical structure and material of the surrounding area. For example, if the surrounding area adopts a non-flat surface, the diopter of the surrounding area deviates greatly, the diopter of the surrounding area changes rapidly, and impurities are added to the surrounding area, etc., each method must consider the blurring effect and appearance.

[0019] According to the imaging principle of glasses, when the difference between the power of the glasses lens and the refraction power of the human eye is large, outside the adjustment range of the focal length of the cle...

Abstract

A small visual field lens is prepared as setting central clear region at center of small field lens, setting around fuzzy region at periphery of small field lens and setting diopter transition region at region between central clear region and peripheral fuzzy region.

Description

technical field [0001] The present invention relates to an ophthalmic lens technology, in particular to a lens that uses the change of refractive power or uses the addition of impurities to divide regions. Background technique [0002] Social anxiety disorder is already a very common mental illness. At present, the treatment of social anxiety disorder can be divided into two methods: psychotherapy and drug treatment. However, psychotherapy is only for guidance, and its effect cannot be determined; the effect of drug therapy can only last for a period of time, and the cost is quite high. Many patients cannot get rid of the troubles for a long time, and their social activities are severely restricted. [0003] The existing progressive multifocal spectacles divide the spectacle lens into upper and lower parts, which are used to see far and near respectively. This design is not and cannot be used to relieve the condition of patients with social anxiety disorder. SUMMARY OF TH...
