How can extended wear lenses stay fresh without daily cleaning?
You may think that lenses get dirty and that without daily cleaning they can lead to eye infections. However you can stop worrying because they have a special coating that reduces the build-up of proteins and bacteria. This is important because it is these proteins and bacteria that can lead to eye infections.
If small dust particles accumulate on the lenses you may need to take them out and clean them. To avoid this inconvenience, you should stay away from dusty rooms and cigarette smoke. Try not to get water in your eyes when you shower and use goggles while swimming. Never use lenses longer than your optician recommends.
If you do take out the lenses out you must clean them thoroughly before putting them back in, it is therefore important that you have access to the contact lens solution.
The history behind Extended Wear lenses
Extended wear lenses became popular back in the 1970’s and 80’s. What separated these lenses was their high water content of 55-70%, unlike traditional lenses whose water content was 38.5%. However, their popularity quickly sank when it emerged that several wearers of these lenses had problems, mainly caused by infections of the cornea. The lenses were made from a hydrogel polymer with didn’t allow a good flow of oxygen to the eye. The eyes of people who slept with their lenses in did not receive enough oxygen which lead to infections. Additionally, the high water content dried out after time which enabled bacteria to grow. This led to the individual’s vision becoming blurred and long term damage to the cornea. Oxygen flow to the eye was not as simple as early developers thought and it unfortunately led to eye infections becoming ten times more common in people who sleep with their lenses in. In the mid-1980s most opticians stopped recommending extended wear lenses. Despite this demand for the product continued so researchers worked hard to develop materials for extended wear lenses. In 1999 new extended wear lenses made of Silicon Hydrogel came on the market. Thanks to the silicone the eye has a good oxygen flow and the extreme comfort of hydrogel, extended wear lenses can now be worn for several days and nights on end.
