Is contact lens hydrogel better or silicone hydrogel better?

Silicon hydrogel is good. Hydrogel is a traditional contact lens material, which mainly transmits oxygen through water, and its ability is limited. Silicon hydrogel is a later developed material. Through the simultaneous transmission of oxygen by silicon and water, the oxygen permeability is greatly improved. Lenses with high water content are easy to dry eyes and have small molecular gaps, which is better for long-term eye health.
