Abstract

An ophthalmic lens material includes an organic monomer, a crosslinker, an initiator, salts and a solvent comprising water. The ophthalmic lens material includes the salts which can be dissolved in water in order to release various anions and cations. These anions and cations can be bonded to water molecules, so that due to the bonding effect, high combination strength between the anions and / or cations and the water molecules is achieved; therefore, in the water solution containing salts, when water molecules are evaporated, the material cannot be evaporated before the bonding effect between the anions and / or cations and the water molecules is broken. In the ophthalmic lens material containing salts, the water molecules are slowly to evaporate, thus achieving long-acting moisturizing effect. An ophthalmic lens made from the ophthalmic lens material can be moisturized for a long time, and can avoid eye diseases, such as dry eyes, pinkeye and the like, due to water loss. In addition, theinvention also relates to an ophthalmic lens produced from the ophthalmic lens material.

Description

technical field [0001] The invention relates to an ophthalmic lens material and an ophthalmic lens made by using the ophthalmic lens material. Background technique [0002] In recent years, with the increasing number of myopic people, contact lenses have been widely used because of their portability and aesthetic characteristics. In addition, for people with high myopia, the transparent lens (lens) is generally removed, and then an intraocular lens (artificial lens, etc.) is implanted, so that the person with high myopia can see objects clearly. However, existing ophthalmic lenses are prone to dehydration, causing dryness or redness of the eyes, making the wearer feel uncomfortable, and even causing eye diseases. Contents of the invention [0003] In view of this, it is necessary to provide a new ophthalmic lens material to solve the above problems. [0004] An ophthalmic lens material includes organic monomers, crosslinking agents, initiators, salts and solvents, and th...
