Silicone Hydrogel: Innovation in contact lensesPam Anderson aside, silicon can actually do more than just enhance that part of the human anatomy; it's actually responsible for helping thousands of people cope with their vision problems. Through silicon contact lenses, of course. Or, more specifically, silicone hydrogel contact lenses – perhaps the most important advancement in contact lens technology in recent years. "Perhaps the most important advancement in contact lens You'll be surprised to know that silicone hydrogel lenses came about more than two decades ago, beginning with the technical challenge of combining oil and water (never an easy thing to do!) to create a contact lens that could deliver maximum oxygen while maintaining eye health. After several years of research and resources, such lenses are now available for everyone to wear. Just take a quick look at the benefits of silicone hydrogel contacts:
True, silicone hydrogel lenses are significantly more rigid than their conventional counterparts, but this increased rigidity makes the lenses easier to handle. 
Protein and lipid build-up has long been an issue with contact lenses. Silicone hydrogel contact lenses have been proven to minimize such deposits. Indeed, when combined with the correct replacement schedule and appropriate care system, the problems associated with natural deposits have all but disappeared.
A problem frequently encountered by wearers of traditional soft contact lenses is the feeling of "grittiness" in the eyes as the day ends. According to recent study group composed of 500 regular soft lens wearers who experienced significant end-of-day dryness, wearing silicone hydrogel lenses can dramatically reduce such discomfort. Silicone hydrogel lenses help you keep up with your active schedule. In fact, in a dozen adverse environments (e.g., traveling by plane, driving at night, using a computer, reading, and sitting in an air-conditioned or heated car, et. al.), the study participants had nothing but praise for the silicone hydrogel lenses. "Contact lens wearers frequently put up with environmentally-triggered discomfort because they need to continue wearing lenses while working, traveling, or in other situations," explains study co-author Robin Chalmers, O.D., F.A.A.O., an independent clinical researcher specializing in contact lens epidemiology. "Left unmanaged, these exacerbating conditions may compromise their ability to wear contacts comfortably throughout the day. After being refit with newer types of silicone hydrogel lenses, contact lens wearers reported significantly improved comfort in most environments." "Contact lens discomfort or dryness are most often cited as the reason people stop wearing contact lenses," adds Dr. Chalmers. "The experience with silicone hydrogel lenses demonstrates why these lenses are rapidly becoming the standard of care for soft lens wear." Are silicone hydrogel lenses really the pinnacle in contact lens technology and comfort? Several signs say yes, but why not find out for yourself?
