Water content

Note: Higher moisture does not mean better

Why: After wearing high-humidity lenses, they will be more moisturizing and comfortable. However, after wearing contact lenses for a long time, the contact lenses themselves will lose water due to evaporation. In order to maintain the original moisture content, it is a sponge-like polymer structure that can absorb the moisture in the eyeballs, resulting in dry eyes.
Low moisture levels can cause insufficient breathing in the pupils, which can lead to hypoxia and red blood vessels.
