Zoom hard contact lens and manufacturing method thereof

Abstract

The invention discloses a variable-focus rigid contact lens and a manufacturing method thereof, a variable-focus corneal shaping device comprises a rigid contact lens and a lens enclosure sealed to a convex side of the rigid contact lens, and a concave surface of the rigid contact lens is configured to be removably mounted on a cornea; a zoom element is arranged between the hard contact lens and the transparent sealing shell, the zoom element spans the central area of the lens sealing shell, the hard contact lens and the transparent sealing shell are in partial entity contact, and on the basis of improving the ability of a brain to recognize image information, the image information can be recognized by using a liquid crystal zoom technology; an object is regularly imaged in front of the retina, on the retina and behind the retina of a wearer, so that the trainer can obtain effective visual training in different focal depth ranges during training, the reaction speed of brain integration optic nerves is increased, the fault-tolerant capability is improved, and the visual effect is improved within a certain focal depth range of clear visual objects during actual naked eye visual object. Therefore, the fuzzy adaptive capacity of the brain is improved.

Description

technical field [0001] The invention relates to the field of optics, in particular to a variable focus hard contact lens and a manufacturing method thereof. Background technique [0002] Due to the great pressure of study and work in modern society, more and more people suffer from vision problems such as myopia, presbyopia, and amblyopia. In the current technology, methods such as wearing glasses, surgery, visual function, and physiotherapy are generally used to restore vision. Wearing glasses can only achieve vision recovery under the condition of wearing eyes, which has the disadvantage of treating the symptoms but not the root cause. When people do not wear glasses, their vision will be affected, so there are limitations in their application. Visual function and physical therapy (such as massage) for relaxation training of internal and external muscles of the eye is effective for pseudo-myopia, but not effective for true myopia, so there are also limitations in its appl...

AI Technical Summary

Problems solved by technology

Since the existing training glasses equipment can only be trained in the two modes of foggy vision and best vision (the focal depth between the best vision and blurred vision is not effectively trained within a certain range), the brain integrates the optic nerve The reaction speed becomes slower and the fault tolerance becomes lower. When actually seeing objects with the naked eye, within a certain range of depth of focus that should be able to clearly see objects, they cannot effectively see objects clearly, which will affect the visual recovery of trainers.

[0004] At present, the main function of the existing orthokeratology lens is to prevent the growth of the eye axis and prevent the development of myopia, but it cannot improve the visual acuity. Alvarez zoom glasses that can improve the visual acuity are realized under the control of the Gabor function. The zoom solution is to improve the blur adaptability, and then improve the naked eye vision, but the weight of the Alvarez zoom glasses is about 100 grams, which is too heavy, and the user will be too uncomfortable to wear, and it is not easy to use, so the user's adaptability is not improved. , the treatment rate is low, and the degree of acceptance is low. Therefore, according to the existing problems, it is necessary to invent a kind of glasses that can prevent the growth of the eye axis and can improve the naked eye vision;

[0005] The patent with the existing application number CN106461973A provides an eye-mountable device that provides automatic adjustment and its manufacturing method discloses an eye-mountable device that provides automatic adjustment, wherein the eye-mountable device includes a lens seal The shell, the front electrode, the rear electrode, and the adjustment actuator element, the front electrode and the rear electrode used in it make the structure too complicated, and the zoom adjustment ability is not strong due to the setting of the front electrode and the rear electrode during use. This invention is mainly aimed at the old For presbyopia patients, it is a technology to correct presbyopia vision by moving the original presbyopia glasses to contact lenses. The glasses become automatic zoom glasses. When the zoom contact lens is not worn, the vision returns to the original state, and the naked eye vision of the user cannot be improved.
