These lenses are not easily torn and the materials they are comprised of contain no water.
This keeps lipids and protein from your tears building up on your lenses.
Made of stiffer materials,
gas permeable lenses make sure the lenses keep their shape when you blink; giving you sharp, clear vision.
These lenses can last for years if taken care of properly, and if your prescription does not change.
Gas permeable lenses are the first choice for people who do not receive the desired visual acuity from soft contacts.
Gas permeable contacts come in many different designs for bifocal contact lens wearers suffering from presbyopia.
