Extended Wear Contact Lenses - An Alternative To Laser Surgery
Contact lenses would be a brilliant alternative to wearing spectacles...if it wasn't for the cleaning, storing, insertion and removal. In fact, when you think about it, the whole business of being a contact lens wearer is a real pain! Despite this, we continue buy them because we like being spectacle-free.
What if you could wear contact lenses without having to clean and disinfect them? What if you could go to bed without having to think "have I taken my contact lenses out"? What if you could have an extra five minutes in bed every morning because you didn't have to clean and insert your contact lenses?
Extended wear contact lenses make all the above scenarios possible. You can now put in your lenses and leave them in all day AND all night without a second thought for up to 7 or 30 days, depending on the brand chosen by you and your eye doctor. At the end of the lenses' life, you just remove them and put in a new pair. It's that simple!
While there is a wide range of extended wear contact lenses designed for 7-day use, there are currently only two brands of 30-day lenses available; CIBA Vision's Night & Day, and Bausch & Lomb's PureVision (Pure Vision is not currently sold in the U.S because of a patent dispute, but is available via European online merchants).
In the past opticians were reluctant to prescribe extended wear lenses, especially 30-day contact lenses, because of concerns about the increased risk of eye infections, but the new generation of continuous wear lenses are made from new, highly permeable silicone hydrogel materials. This lens composition provides much more oxygen to the eye than most conventional extended wear contact lenses, For example, Night & Day lenses reportedly allow six times more oxygen to pass through the lens than typical disposable extended wear lenses.
If you hate all the fuss and bother of wearing contact lenses, but can't afford/face laser eye surgery, it's time to give continuous wear lenses a trial!
