The application of contact angle measuring instrument in the research of contact lens

2022-04-13

Globally, the number and quantity of contact lenses are very large, of which hydrogel contact lenses account for the largest proportion; hydrogel contact lenses are made of hydrophilic polymers. In order to avoid discomfort during wearing, contact lenses need to meet some specific requirements, including sufficient air permeability, lens movement and surface wettability. Contact angle is one of the methods to test the wettability of solids, and this is determined by measuring the contact angle meter.

The inside of our eyes is relatively moist, and contact lenses are used to prevent dry eyes and eye fatigue after wearing them. Therefore, the contact angle meter needs to be used to measure the contact lens during production. The smaller the contact angle of the contact lens, the stronger the hydrophilicity, the better the effect of the contact lens, so as to better serve the consumers of the contact lens.
