Description

An adjustable spectacles for refractive correction

technical field

The invention relates to the technical field of spectacles, in particular to adjustable spectacles for refractive correction.

Background technique

In recent years, based on genetics and changes in modern lifestyles, myopia has become an eye disease with a very high incidence, especially among children and adolescents. According to relevant reports, the myopia rate of children and adolescents has reached 80%. Because the eyeballs of children and adolescents are in the growth and development stage, if they are not corrected in time, the excessive development of the retina will lead to an increasing degree of myopia. Therefore, refractive correction is of great significance.

Refractive correction is to adjust and move the clear image that cannot be accurately presented on the retina to a specific position of the retina through some means, so that people with refractive errors can obtain clear vision. The correction of myopia in the prior art mainly includes OK lenses and orthokeratology lenses, which are used for refractive correction. At present, more and more people use orthokeratology lenses, and some wearers cannot wear them continuously due to cornea, lens and personal reasons. OK lens, the refractive state is unstable, and the daily change is relatively large. It cannot be corrected with a single eyeglass, which brings great inconvenience to study, life and work.

Chinese patent document CN201220181177.2, application date 2012.04.26, patent name: a kind of myopia correction glasses, discloses a kind of myopia correction glasses. It includes correction lenses and spectacle frames, and is characterized in that the correction lenses are convex lenses. Considering that teenagers are in the stage of growth and development, the adjustment ability of the eyeball is very strong. After wearing a convex lens, in order to change the amount of light entering the eyes, the ciliary muscle actively relaxes to adjust the lens to shorten the eye axis, thereby alleviating eye ciliary muscle spasm. Compared with ordinary myopia glasses, this kind of myopia correction glasses reduces the near adjustment of the eyes, can achieve the purpose of eliminating visual fatigue, improving and even treating pseudomyopia, and the effect is good.

Chinese patent document CN201410496190.0, application date 2014.09.25, patent name: a kind of corrective glasses, discloses a kind of corrective glasses, including a frame, temples, lenses, nose bridge, the two sides of the frame can be folded and connected to the temples , the lens bag is embedded in the frame, the end of the mirror leg connected to the frame is provided with a tape measure, the tape measure is provided with a connecting hole, and the tape measure is provided with a telescopic rod as described in the telescopic rod. One end of the telescopic rod is connected to the connection hole, and the other end is connected to the desktop. The bridge of the nose is provided with a small light, and the temples are provided with a button battery. connected, the spectacle frame is provided with a spectacle cover, and the spectacle cover is detachably connected with the spectacle frame. The spectacles can correct the sitting posture of the students and the correct distance between the spectacles and the books, enhance visual light, relieve visual fatigue, and help the students' eyesight slowly deepen.

The above-mentioned patent documents use a convex lens to increase the amount of incoming light and change the sitting posture to correct myopia, but there is no disclosure about glasses that can adjust the appropriate degree according to different refractive states every day.

To sum up, there is an urgent need for adjustable glasses for refractive correction that can adjust the appropriate degree according to different refractive states every day. And about this adjustable glasses that are used for refractive correction, there is no report yet.
