Contact Pink Cat Eye Glasses lenses rely on water to transmit oxygen, the lower the water content, the worse the oxygen permeability of the Blackpink Glasses lens, not easy to corneal health. But low water content lenses shape better. To solve the oxygen permeability problem with low water content, the Light Pink Glasses lens can be thinned. Because the low water content lens contains less water, the lens itself carries less load. If you need to buy a low water content lens, the center thickness can be relatively thin, so his oxygen permeability will be relatively good. But the center of the Cute Black Glasses lens should not be too thin. Because too thin lens molding is not good, in addition to the evaporation of tears will speed up, but cause dry eyes. Therefore, the oxygen permeability of hydrogel lenses with low water content is limited.
