Multifunctional myopic control eyeglass

Abstract

The invention relates to a multifunctional myopic control eyeglass. The eyeglass which comprises a glass frame with height-adjustable nose supports, and eyeglasses is characterized in that: each eyeglass comprises an upper far luminosity zone, a middle zone and a lower close reading zone; and there is a visual channel with two degree changes, wherein one degree change is between the optical center of the upper far luminosity zone and the optical center of the middle zone just below the upper far luminosity zone, and the other degree change is between the optical center of the middle zone and the optical center of the close reading zone just below the middle zone. The eyeglasses are specially divided into three zones for the zero adjustment and the zero aggregation of reading and writing in the invention, so problems of the adjustment and the aggregation of close range reading and writing are thoroughly solved, the visual fatigue is eliminated, and myopia and degree increase are prevented, thereby present computer times of the comprehensive eye utilization are complied. The multifunctional myopic control eyeglass which allows previous neglected computer groups to be substantially facilitated allows the visual field to be clear, real and stable through the humanized zone height of each zone of the eyeglasses. The three zones which are used for cooperating with the adjustment of the eyeglass frame allow an image jumping phenomenon to be avoided. The wearing position of the eyeglass is accurate to guarantee the correct utilization of each zone, prevent the generation and the development of myopia caused by the fatigue of internal and external muscles of eyes and ciliary muscles.

Description

technical field [0001] The invention relates to glasses for preventing and controlling myopia, in particular to a multifunctional myopia controlling mirror for students and computer workers. Background technique [0002] The etiology of myopia: environmental factors, genetic factors and others. Among them, myopia caused by environmental factors is the most common, and it is mainly caused by excessive close work. Long-term close work mainly leads to fatigue of the internal and external ocular muscles and ciliary muscles, manifested as excessive and / or uncoordinated adjustment and collection. [0003] When the corrected emmetropia or myopia eyes gaze at the distance, the inner and outer ocular muscles of the eyes are in a relaxed state, the visual axes of the eyes are parallel, and the set is zero. The ciliary muscles of both eyes are also in a state of complete relaxation, and at this time the adjustment of the lens of the eye is zero. The pressure inside the eye is not ch...

AI Technical Summary

Problems solved by technology

However, these glasses are mostly used for the qualitative application of convex lenses and prisms to reduce the adjustment and concentration, but they have not done a good quantitative study on the relationship between them and the reading distance, eye position and interpupillary distance, so that the inner and outer eye muscles and ciliary muscle not fully relaxed

At the same time, the glasses are heavy and cannot be used far away, so the prevention and control effect is not perfect
