Description

Glasses for protecting retina

Technical Field

The utility model relates to a glasses field, concretely relates to glasses of protection retina.

Background

The glasses are common articles in daily life of people, and have various varieties, such as myopia glasses, presbyopic glasses, astigmatic glasses, wind and sand prevention glasses, sunglasses and the like, wherein the sunglasses have certain light blocking and filtering functions, and other glasses have no light blocking and filtering functions.

The eye imaging development, the light from the outside of the eye is directly irradiated into the eye without more attenuation or filtering, thus, the scene light reaches the retina imaging through the dioptric system, part of the main scene light enters the eye and is focused on the macular area of the retina for clear imaging, part of the scattered light irradiates on the retina around the macular area for fuzzy imaging, and the process of the eyeball development towards the emmetropia state or the myopia state is formed after the condition is maintained for a long time.

In the current society, the myopia rate of teenagers is higher and the teenagers are younger, which is mostly caused by the over-use of eyes in a short distance, long illumination time of the eyes, high illumination intensity and abnormal light radiation. As known, the macula lutea is located in the center of retina and is the most sensitive area of vision, the vision of the retina outside the macular area is extremely low, the vision of the retina outside the macular area plays an important role in the development of eyeballs, the illumination is more, the development of the eyeballs is accelerated, the illumination is less, the development of the eyeballs is slowed, and the light entering the eyes is irradiated on the retina of the back half parts of the eyeballs for a long time to cause progressive increase of cells and sclera of the back pole parts of the eyeballs, so that the axis of the eyes is lengthened, the axis of the eyes is excessively increased, and the axial myopia is easily formed. Thus, there is a need for a method or product that can effectively reduce the amount of light radiation from the retina outside the macular area, and slow down the progression of the eyeball to the emmetropic state or the myopic state, while the commercial spectacle products do not have the differentiated light radiation protection effect on the retina outside the macular area and the retina outside the macular area of the eyeball.

In conclusion, the problem of high irradiation amount of light entering the eyeball is solved, the retina is protected in a subarea manner, the speed of the eyeball developing to the emmetropia state or the myopia state is slowed down, and therefore the purpose of preventing myopia or slowing down myopia is achieved.
