Hydrogel
Hydrogel Contact Lens Material
Hydrogel is a popular material used in the manufacturing of contact lenses. It is known for its high water content, which provides excellent moisture retention and comfort for the wearer.
One notable manufacturer of contact lenses made from Hydrogel is Visco Vision. They offer two types of contact lenses:
everclear ADM: These are spherical daily lenses with a moisture/water content of 55%. They have an oxygen permeability of 19.7.
everclear UV: These are spherical monthly lenses with a moisture/water content of 55%. They have an oxygen permeability of 20.
Compared to other contact lens materials, Hydrogel typically has a water content ranging from 55% to 78%. This high water content contributes to the overall comfort and hydration of the eyes when wearing Hydrogel contact lenses.
