contact lenses - Silicone-hydrogel

Silicone hydrogel is the newest material in contact lens production. The hydrogel component helps ensure a high water content, and the silicone provides high oxygen permeability. Today, lenses made from silicone-hydrogel material are more comfortable than ever - thanks to their moisture and breathability- and they are an excellent choice for people with dry eyes. Because silicone-hydrogel lenses have such high levels of oxygen permeability, many varieties are approved for continuous wear. Although it’s convenient, continuous wear does come with a higher risk of eye infection. Always discuss this with your optometrist before beginning a continuous wear regimen.
