Learn All About Silicone Hydrogel Contact Lenses

Silicone hydrogel contact lenses have stirred in a revolution in the world of contact lenses. Made from silicone polymer, these contact lenses offer much more comfort and moisture to your eyes, as compared to other contact lenses.

What are Silicone hydrogel contact lenses?
Silicone hydrogel contact lenses are a new type of contact lenses that offer extreme permeability. As compared to any other contact lens, they can offer huge amount of oxygen to your cornea which keeps your eyes refreshed at all times. There are some silicone hydrogel contact lenses that can be worn for 30 consecutive days.

How are they different from other contact lenses?
What makes these contact lenses different from others is their ability to provide oxygen to the eyes. They allow your eyes to breath up to five to six times more oxygen as compared to other contact lenses. This makes them a lot more comfortable than any other contact lens available in the market.

Most contact lenses available in the market make use of polymer, which is not oxygen permeable. Therefore, these lenses use the water present in the lens to transport the oxygen from the surrounding areas to the eyes. However, the water alone cannot transfer enough oxygen to the eyes. Of course, there is an option to opt for contact lenses with a high water content. But, higher the water content of these contact lenses, the greater are the chances of dehydration after extended periods of wear.

On the other hand, silicone hydrogel contact lenses make use of silicone which is oxygen permeable. These contact lenses make use of both the water as well as the silicone polymer for the purpose of transmitting oxygen to the eye. It is for this reason that silicon hydrogel contact lenses make use of less water as compared to other contact lenses. This means that these lenses will not dehydrate even if you wear them for extended periods of time. This means increased comfort for contact lens wearers.
