Description

Corneal contact lens wearing tool

Technical Field

The utility model belongs to the technical field of the contact lens wearing tool, concretely relates to contact lens wearing tool.

Background

The corneal contact lens CL is directly attached to the lacrimal fluid layer of the cornea, is physiologically compatible with human eyes and achieves the aim of vision correction. Compared with orbital frame glasses, CL has a larger visual field, can keep optical correction performance in all watching directions, eliminates the prism effect of the glasses, eliminates oblique astigmatism, reduces retina aberration of eyes, keeps better binocular vision, is safe, convenient and attractive to use, and also has some special lenses which can meet some special requirements. Indications are as follows: is especially suitable for high myopia, corneal astigmatism, refractive error, aphakic eye, etc.

At present, soft corneal contact lenses SCL are mainly used for correcting myopia in China, the main wearing mode is the traditional type or the frequently-replaced type, the SCL is large in water content and diameter, good in attachment during wearing, comfortable and strong in adaptability, and the new progress is towards daily disposable type and long wearing type.

The rigid air permeability corneal contact lens RGP has the advantages of being superior, high in oxygen permeability of materials, safe to use, simple and convenient to nurse, and capable of well correcting myopia, astigmatism and optical characteristics of keratoconus, and seems to have a clinical phenomenon of preventing or slowing down myopia progression of children according to preliminary research. The usage rate of RGP is very common in developed countries, and is the most healthy vision correction choice accepted in clinical ophthalmology, and there is a good development trend in China, and more myopia patients begin to recognize that RGP has greater superiority than SCL.

Corneal reshaping mirror (commonly called OK mirror) is a lens designed by inverse geometry, which can mechanically press or massage cornea to enlarge its central curvature radius, reduce the refractive power of cornea and improve distant vision.

The wearing methods of the corneal contact lenses are that the corneal contact lenses are directly worn on the cornea of the eyeball by finger operation, and due to the fact that the wearing methods are complicated and the operation processes of users are mostly irregular, the corneal contact lenses are easy to fall off from the fingers and often deviate when being worn, and then the corneal contact lenses are worn repeatedly, secondary pollution is easy to form, inflammation of eyes is caused, troubles are brought to the users, and no corneal contact lens wearing tool matched with the corneal contact lenses is available in the market at present.

In view of the above, we propose a corneal contact lens wearing tool so as to solve the problems set forth above.

Disclosure of Invention

An object of the utility model is to provide a corneal contact lens wearing tool, wear the method with the present various corneal contact lenses on the market that solve above-mentioned background and put forward and all directly wear the corneal contact lens on the cornea of eyeball with finger operation, because of the difference of user age, in addition wear the method loaded down with trivial details, user operation process is mostly all nonstandard, make easy the following finger drop when wearing the corneal contact lens, and often can the off normal, and then wear repeatedly, easily form secondary pollution, arouse the eye inflammation, bring inconveniently for the user, and do not have the problem of exclusive supporting corneal contact lens wearing tool again on the present market.
