If we talk about hydrogel lenses, then water is responsible for delivering oxygen to the surface of the cornea, so the more it is, the better. However, it is impossible to achieve higher oxygen permeability in lenses made of such materials, since with an increase in the water content in the polymer, the thickness of the lens increases, which leads to a decrease in this indicator.
