Since 1999, day and night contacts have benefited a lot of patients with impaired visions. These contacts are prescribed for vision correction for those with myopia or hypermetropia, nearsightedness and farsightedness respectively. In contrast with its traditional counterpart, these extended wear contact lenses are made from silicone hydrogen material that lets oxygen pass through to the cornea. The traditional soft contact lenses are of hydrogel polymer materials that do not let oxygen pass through. Traditional lenses need to be taken out periodically for washing and disinfecting while extended wear contact lenses can be worn day through night for a period of thirty days. Proponents of these contact lenses have secured the approval of the US Food and Drugs Administration (FDA) for the commercial release of these lenses. Through the years, the benefits of such lenses have been enjoyed by millions of busy people. Sales reports show that sales of extended wear contact lenses account for about 60% of contact lens revenues.
There are both advantages and disadvantages to wearing day and night contacts. The best person to tell you whether it is safe for you to wear this kind of contacts would be a qualified eye care professional. Consulting your eye care professional would give you a clearer idea of the current state of health of your eyes including any risks that you could face by wearing contacts day through night for a number of days. Overall, the benefits of these contacts far outweigh the risks especially once you have been cleared by your eye care professional. These contacts remain to be a great vision correction option for busy people all over the nation and the world.
One main benefit of day and night contacts is that you do not have to take them out from time to time in order to clean it and let your eyes breathe. You can leave the lenses securely placed on your cornea for days without having to take them out to ease feelings of dryness. The silicon hydrogel that these lenses are made of allow about six times more oxygen to pass through the lens into the eyes. These contacts are also 24% made of water. This makes the contacts less prone to dehydration – the cause for needing to take out traditional contacts at the end of each day. Often, the more water the traditional contact lenses contain, the faster it gets dehydrated. There is no need to worry about this happening with extended wear contact lenses.
Another benefit of day and night contacts is that it reduces the chances of your eyes being infected. This is because these lenses do not let much harmful bacteria build up. It also lessens chancess of corneal swelling and eye infection. Such results of wearing such contacts are often compared to the results of lasik eye surgery. It could be considered as a less expensive vision correction alternative to undergoing lasik eye surgery. It is a cheaper, more convenient, and less riskier way to enjoy clear vision that is why it has become so popular.
