Problems solved by technology

[0003] However, most of the existing contact lenses are used to correct vision or treat eye diseases, and their functions are relatively single. For example, if they cannot block the unnecessary light that is harmful to the eyes from around the pupil, they cannot play the role of sunglasses.

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0025] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0026] figure 1 A high-definition contact lens with anti-ultraviolet and diffracted light functions in an embodiment of the present invention is shown, including:

[0027] Lens base layer 1, which is a curved transparent structure matching the eyeball cornea, the middle part of the lens base layer 1 is an optical zone, and the optical zone is a circular area with a diameter of 6.3 mm to 8.0 mm;

[0028] The translucent light-shielding layer 2 is attached to the surface of the lens base layer 1 away from the cornea of ​​the eye and is located at the periphery of the optical zone....

Abstract

The invention discloses high-definition contact lenses with an ultraviolet ray and diffracted light resistant function. The high-definition contact lenses comprise lens substrates and semitransparent light shading layers, wherein the lens substrates adopt a cambered-surface transparent structure matched with a cornea of an eyeball, the middle parts of the lens substrates are optic zones, and the optic zones are circular regions of which the diameters are 6.3-8.0 mm; the semitransparent light shading layers are attached on the surfaces, far away from the corneas of the eyeballs, of the lens substrates and positioned on the peripheries of the optic zones, and the semitransparent light shading layers are used for shading high-strength light. According to the high-definition contact lenses disclosed by the invention, unnecessary light which is damaged to eyes and entered from positions around pupils is shaded by utilizing the semitransparent light shading layers, the high-definition contact lenses are suitable for people to wear under environments of high-strength sunlight illumination, or environments using computers, or televisions or cellphones, or in a workshop and the like, through the control of the diameters of the optic zones in the circular regions, enough visual space is ensured, and the light transmissivity is as high as 95%.

Description

technical field [0001] The invention relates to a contact lens. More specifically, the present invention relates to a high-definition contact lens with functions of anti-ultraviolet and diffracted light, which is worn and used in environments such as computers, televisions, mobile phones or workshops. Background technique [0002] Contact lenses, also called contact lenses, are lenses worn on the cornea of ​​the eye to correct vision or protect the eyes. Contact lenses not only improve myopia, hyperopia, astigmatism, etc. Light is not correct for patients with great improvement. Moreover, it has a wide field of vision and realistic vision. In addition, it has also played a special role in controlling the development of myopia and astigmatism in young people, and treating special eye diseases. [0003] Yet existing contact lenses are mostly used for correcting eyesight or treating eye disease, and function is comparatively single, for example, can't play the effect of sungl...
