Pseudo-myopia correction glasses

technical field

The invention relates to an ophthalmic treatment instrument, in particular to a pseudo-myopia correction glasses.

Background technique

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 only can a clear object image be formed on the retina quickly, but also images can be imaged on the symmetrical positions of the retinas of both eyes. Then, the photoreceptor cells activated by the sensation transmit the imaged information to the visual center of the occipital cortex of the brain through the neural visual pathway (visual pathway), and finally obtain binocular vision, and the objects seen at this time will be very clear. However, when the regulation mechanism of this complex physiological response is damaged by various factors inside and outside the body, such as long-term fatigue eye use, the adjustment tension and spasm of the ciliary muscle and the orbicularis muscle around the orbit are caused. The adjustment cannot be relaxed when touching objects, which will inevitably change the refractive system of the human eye over time, resulting in refractive error, and according to the damage and degree of the refractive adjustment response system, one after another suffer from pseudomyopia of different nature and degree .

Clinically, the eyeball has two sets of inner and outer muscles. The inner muscles are the iris (pupil sphincter) and the ciliary muscle, which can adjust the size of the pupil and the focal length of the lens. There are six external muscles that control eye movement.

In my country, the myopia rate of teenagers is close to 70%, which is mainly caused by long-term watching TV, surfing the Internet, playing games, etc. without paying attention to eye use. There are also incorrect reading and writing postures, books placed too close to the eyes, and poor lighting conditions. These will make the muscles in the ciliary body continue to contract, and the F degree of the lens will increase, so that the muscles in the ciliary body will be in a tense state, and the F F lens cannot return to the normal state, thus causing pseudomyopia.

Previously, the common methods of correcting pseudomyopia mainly include:

1. Excimer laser myopia surgery, through cutting the cornea, making a corneal flap, and then using laser to act on the cornea to achieve the purpose of correcting refractive errors. 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.

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 don't pay too much attention, so it may not be able to achieve the expected effect.

At present, although both methods of excimer laser myopia surgery and lens correction can achieve the purpose of correcting myopia, they still have certain defects.
