More and more people now realize the advantage of using contacts, thus they switch to this product and hide their old-fashioned eyeglasses inside their closets. The rising popularity of contact lens led to the invention of more comfortable and efficient versions, the most popular type of lens in eye-wear industry today is the silicon hydrogel type of lens.
Made up of silicon polymer, this type revolutionized the world of eye-wear today as it is significantly more comfortable to use (because of its substance that helps moisture the eyes) as compared to other lenses.
If you are not an avid user of this eye-wear, you might be wondering what is silicon hydrogel lens is.
Silicon hydrogel lenses are the newest type of its kind available in the market right now. It is the most permeable lens ever invented yet. Thus it allows significant amount of oxygen to pass through the lens and reach the cornea of the eyes. Oxygen helps to replenish and refresh the eyes, its holey feature keeps the eyes fresh at all times. There are versions of this type of lens that can last up to 30 days of consecutive use.
How is this silicon hydrogel different from other contacts?
Most lenses available in eye care shops today is made up of polymer. But polymer is not oxygen permeable; it only uses the water of the lens to send oxygen to the eyes. This however hardly refreshes the eyes as there is not enough oxygen reaching the cornea. There are contacts out there that have high water content, but this type can cause the eyes to dehydrate easily after long hours of using.
In the case of silicon hydrogel contact lenses, you can feel the difference the moment you wear it. Its air-penetrable form allows oxygen to pass through it easily, allowing your eyes to breath oxygen five to six times more than those ordinary contact lenses available in most eye care stores. Its holey form makes wearing the lens a lot more comfortable than its regular counterparts.
