Multifocal contact lenses are similar to spectacles with bifocals

Some have a series of powers in each lens, similar to progressive eyeglasses. Simultaneous visual lenses, for example can correct near, intermediate, or far vision. While segmented and alternative vision lenses offer different power settings, they are suitable for different purposes.
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.
Disposable lenses may be used to replace frequently scheduled or planned glasses.
There are two main types of contact lens: regular disposable or planned replacement.

Due to its torsion, any light that strikes it will cause it to refract. This is because its highest power is in the x and y planes, and its lowest power in its z axis.
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. These include lens truncation (thin-thick zones), and the middle axis.
