Abstract

The present invention relates to an ophthalmic product with cornea repair function. The ophthalmic product having a cornea repair function includes an ophthalmic composition. The ophthalmic composition includes gold nanoparticles serving as the main repairing ingredient and at least one auxiliary repairing ingredient. An effective concentration of the gold nanoparticles is from 0.01 ppm to 3000 ppm. The content of the at least one auxiliary repairing ingredient is greater than 0 wt % and less than 20 wt % based on 100 wt % of the ophthalmic composition. The ophthalmic product can enhance the protection and repairing capacity of cells in each layer of tissues of the eyes, and can improve the wearing comfort of the contact lenses.

Description

technical field [0001] The present invention relates to an ophthalmic product, in particular to an ophthalmic product with corneal repair function, such as contact lens related products or ophthalmic products. Background technique [0002] The cornea is located at the front of the eyeball. The cornea itself is transparent and has no blood vessels. Its source of nutrition is not only the supply of aqueous humor, but the peripheral cornea mainly depends on the limbal vascular network. The cornea has very sensitive nerve endings. Once a foreign object touches the cornea, the eyelids will involuntarily close to protect the eyes. In addition to protecting the contents of the eye, the cornea is also an important part of the refractive system of the eye, similar to the lens of a camera. [0003] Most people with poor vision have the habit of wearing contact lenses for a long time. However, the result of wearing contact lenses for a long time may lead to corneal inflammation and da...
