Abstract

The invention discloses eyeglass for improvement and auxiliary improvement of eyesight through peripheral visual fields and application of the eyeglass. An central visual field of the eyeglass is arranged at the center of the eyeglass; through slight focusing of the eyeglass in a front viewing direction, the optic axis length is guided to be normal gradually; a near-distance peripheral visual field of the eyeglass is arranged between the central visual field area of the eyeglass and an equator peripheral visual field of the eyeglass; through focusing of the eyeglass in the front viewing direction of a vicinity peripheral visual field, force that the peripheral visual field trends to be front viewing is formed, and the optic axis length is guided to be normal gradually; the equator peripheral visual field of the eyeglass is arranged at the outermost area of the periphery of the view, an object image is positioned at a part near the equator of an eyeball and is subjected to reversed focusing out of the central visual field and the near-distance peripheral visual field; force for expanding the diameter of the eyeball equator is formed for shortsightedness, and force for reducing the diameter of the eyeball equator is formed for hyperopia; and furthermore the central visual field and the near-distance peripheral visual field can form the front viewing force, and the optic axis length is guided to be normal gradually.

Description

Technical field [0001] The present invention relates to the technical field of ophthalmic treatment equipment, and more specifically, to a lens that uses peripheral visual field to improve and assists in improving vision, and an application method for borrowing peripheral visual field to improve and assists in improving vision. Background technique [0002] Myopia refers to the fact that the distant target image is focused in front of the retina, resulting in blurring of distant vision. It is a global vision problem. This vision problem occurs in people of all ages and nationalities. [0003] Studies have shown that the increasing degree of myopia is related to the following factors: 1. When looking at distance glasses, the central field of vision object falls behind the retina and gradually lengthens the axial length of the central area; 2. Even when looking at distance glasses, The object in the central field of vision falls on the retina. Because of the spherical shape of the ey...
