Permeable eyeball cover

Abstract

The invention discloses a permeable eyeball cover. The cover comprises a cover body which is attached to the surface of an eyeball and matched with the curved surface of the eyeball, wherein the area, corresponding to the eye pupil, at the center or the off center of the cover body, is of a hollowed-out structure or not; the average thickness of the cover body is 100nm-5mm; a plurality of micro channels are arranged in the surface, closely attached to the eyeball, of the cover body; the depth of the micro channels is less than the thickness of the cover body. The permeable eyeball cover disclosed by the invention has the advantages that the micro channels and / or micro holes are formed in the inner surface of the cover body and communicated with clearances in cover body materials to form a communicated network, so that the flowing, transferring and exchanging of matters between the cover body and the eye ball become more easily and the permeability is increased. The eyeball cover disclosed by the invention has the functions of high-permeability contact lenses, cosmetic contact lenses, special contact lenses, eyeball bandages for visual eye care, drug applying type contact lenses, drug applying type cosmetic contact lenses, eyeball bandages for visual eye medical treatment, eyeball bandages for visual eye medical treatment or combinations of all the functional bodies.

Description

technical field [0001] The invention relates to the technical field of ophthalmic supplies, in particular to a see-through eyeball cover. Background technique [0002] The spherical mask-shaped equipment covering the eyeball in the prior art mainly includes contact lenses and color contact lenses. A contact lens, or contact lens, is a lens that is worn on the cornea of ​​the eye. Contact lenses in the narrow sense are used to correct vision or protect the eyes, and colored lenses in the narrow sense can increase the aesthetic feeling. At present, the functions of contact lenses and color contact lenses have been basically integrated. Contact lenses and color lenses include hard and soft lenses, which not only greatly improve the appearance and convenience of patients with refractive errors such as myopia, hyperopia, and astigmatism, but also have a wide field of vision and realistic vision. It also plays a special role in the development of myopia and astigmatism in young...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the problem that the poor permeability of contact lenses and colored contact lenses in the prior art causes eye hypoxia to cause redness, swelling and disease, and the inability to perform visual behavior after using the ophthalmic bandage in the prior art, the present invention provides a transparent eyeball cover
