Pseudomyopia correction glasses

Abstract

The invention relates to a pair of pseudomyopia correction glasses which comprises a glasses bracket (1) consisting of two glasses frames (2) and glasses legs (4). Insert grooves (2a) are formed in the glasses frames (2), correction eyeglasses (3) are inserted and connected in the insert grooves (2a), motors (7) and power supplies (8) connected through supporting plates (6) are arranged on two sides of the glasses bracket (1) and are connected electrically, a rotary shaft (10) is connected to the output shaft of each of the motors (7), the rotary shafts (10) are connected with front visual charts (13) through connecting rods (12), and the front visual charts (13) are correspondingly matched with the corresponding glasses frames (2). The pair of pseudomyopia correction glasses further comprises a rear visual chart (14), and the rear visual chart (14) is correspondingly matched with the glasses bracket (1) in used. The pair of pseudomyopia correction glasses has the advantages that a physical method is adopted for correction, has the good correction effect on pseudomyopia of adolescents, does not harm eyes and is safe and reliable.

Description

technical field [0001] The invention relates to an ophthalmic treatment instrument, in particular to a pseudo-myopia correction glasses. Background technique [0002] According to the principle of optics, the object distance in the outside world is inversely proportional to the imaging distance in the human eye. When people use their eyes at close range for a long time, they will mobilize the physiological synchronous near reflex adjustment function of the eye, and complete or make up for this by themselves through the refractive adjustment reaction. A process, this process is called the regulatory response in medicine. In the process of this physiological adjustment response, the human eye will successively experience reflexive ciliary muscle contraction, increased refractive power, increased spherical curvature of the lens, converging and elongated visual axes of the two eyeballs, and pupillary constriction. Through this series of physiological adjustment reactions, not o...

Problems solved by technology

Excimer laser is an ultraviolet light beam with a wavelength of only 193 nanometers invisible to the human eye. It is characterized by high photon energy, extremely short wavelength, and extremely weak penetrating power to tissues. It will not penetrate into the eye and is only absorbed by the surface of the tissue. No damage or minimal damage to surrounding tissues, excimer laser corneal refractive therapy (LASIK technology), is to use a special and extremely precise micro-keratectomy system (referred to as keratotomy) to make the corneal surface tissue into a band For the pedicled corneal flap, after flipping the corneal flap, under the control of the computer, excimer laser is used to precisely vaporize the part of the corneal stroma under the flap to be removed, and then rinse under the flap and reset the corneal flap to change The shape of the front surface of the cornea adjusts the refractive power of the cornea so that the external light can be accurately converged into an image on the fundus to achieve the purpose of correcting myopia. Although this method of removing part of the cornea is quick, it will cause certain damage to the eyes and the risk is very high. Big

[0007] 2. Lens correction. Wearing glasses is the most common method for children to correct myopia. The principle of glasses should be the lowest lens that can also correct the vision of myopia to the best vision. However, there are many things to pay attention to and it takes a long time to persist , especially in the tedious life, most of them will not pay too much attention, so it may not be able to achieve the expected effect
