Silicone hydrogel lenses offer higher oxygen permeability than normal water.

Silicone hydrogel lenses offer higher oxygen permeability than other materials. The hydrogel component of click the next page lens material transports fluids. This means that oxygen transmission must be balanced against fluid transport. The lens’ oxygen permeability determines how much oxygen can pass through it. Silicone hydrogel lenses, however, are less “wettable than” water.

Toric contacts correct astigmatism by correcting unevenly curvature of the cornea.

Because of the lens’ tendency slippage and blurred vision, patients with astigmatism might have difficulty wearing regular spherical contacts. click the next page cornea is not a round shape so manufacturers of toric contacts lenses have to use multiple methods to ensure they fit correctly.
