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.
[0022] An anti-ultraviolet contact lens provided by a preferred embodiment of the present invention is mainly composed of a main substrate and an anti-ultraviolet material, and the main substrat...
