Anti-ultraviolet contact lens

Abstract

An anti-UV contact lens mainly consists of a main substrate and an anti-UV material. The main substrate is hydroxyethylmethacrylate (HEMA), the anti-UV material contains an UV blocker and a photo initiator, wherein, the photo initiator basically consists of 2,4,6-trimethylbenzoyldiphenylphosphine oxide and benzoylformate initiator. The anti-UV contact lens can increase productivity without changing the original process, accelerate curing time of the UV blocker, and reduce defective rate.

Description

technical field

[0001] The invention relates to contact lenses, in particular to a contact lens capable of resisting ultraviolet rays. Background technique

[0002] By the way, it is known that in the production process of contact lenses, in terms of prescription, colored clothing, color, etc., all can be customized to meet the needs of users, but there are few on the market that can resist ultraviolet rays. Contact lenses, so users who wear contact lenses often need to use sunglasses to resist excessive ultraviolet rays when the sun is strong. In this way, for users who wear contact lenses, it is a burden. Not only does it cost more to buy sunglasses, but it also violates the original intention of wearing contact lenses, which in turn affects the user's ability to wear contact lenses. The will of eyeglasses, here, known contact lenses do have its place that can be improved.

[0003] In order to solve the defects of the previous disclosure, it was developed to add ultravio...

Examples

Embodiment Construction

[0020] The anti-ultraviolet contact lens of the present invention is mainly composed of a main substrate and an anti-ultraviolet material, the main substrate is hydroxyethylmethacrylate (HEMA), and the anti-ultraviolet material includes : UV absorber (UV blocker) and photoinitiator (photoinitiator), wherein the photoinitiator is basically made of 2,4,6-trimethylbenzoyl diphenylphosphine oxide (2,4,6 -Trimethylbenzoyldiphenylphosphineoxide) and benzoylformate initiator (Benzoylformate initiator).

[0021] Therefore, through the above design, the present invention can achieve the anti-ultraviolet effect by adding ultraviolet absorbers and photoinitiators without changing the original process, and can accelerate the curing time of the ultraviolet absorbers and reduce the defective rate.
