Diopter-variable myopia-preventing photochromic glasses

Abstract

The invention relates to a pair of myopia-preventing photochromic glasses with variable diopters. The pair of myopia-preventing photochromic glasses comprises a glasses frame, lenses, a micro camera, a liquid crystal, a controller and a plurality of micro LED chips, a flat elliptical area taking the intersection point of the optical axis of the pupil surface and the lens as the center is a light-transmitting area of the lens; the micro camera is arranged on the glasses frame and used for collecting pupil pictures of a wearer and obtaining the central position and the visual axis of a pupil surface according to the pupil pictures; the liquid crystal is arranged on the lens and used for adjusting the refractive index of the lens light-transmitting area so as to change the diopter of the lens light-transmitting area; the controller is used for controlling the voltage of the electrodes at the two ends of the liquid crystal to adjust the refractive index of the light-transmitting area of the lens according to the central position and the visual axis of the pupil surface acquired by the micro camera so as to change the diopter of the light-transmitting area of the lens; and the plurality of micro LED chips are arranged in the glasses frame around the side edges of the lenses and are used for emitting light with preset central wavelength. The device can effectively help the movement of ciliary muscles, prevent the depth of field of human eyes from being reduced, and prevent myopia from deepening.

Description

technical field [0001] The invention belongs to the technical field of spectacles, and in particular relates to anti-myopia color-changing spectacles with variable diopter. Background technique [0002] Myopia refers to the distant view passing through the refractive system of the human eye and being imaged in front of the retina instead of on the retina. China is a big country with myopia, and 70% of teenagers are myopia, so it is of great significance to study the prevention and treatment of myopia. [0003] Adopting far-sighted glasses is a kind of method of myopia prevention and treatment at present. There are three types: 1. Virtual focus hyperopia lens (i.e. virtual focus hyperopia lens): It can virtualize the refractive focus when looking at near to a distance beyond 5 meters, directly offset "seeing near", and provide hyperopia distance Focus (front defocus), counteract the defocus of the peripheral vision when looking close, such as wearing virtual focus telephoto...

Problems solved by technology

[0008] In view of this, the purpose of the present invention is to overcome the deficiencies of the prior art and provide a kind of anti-myopia color-changing glasses with variable diopter to solve the myopia caused by the increase of the eye axis caused by peripheral light and the lack of movement of the ciliary muscle in the prior art. , lack of dopamine hormone, and inaccurate lens diopter induced myopia
