Extended Wear Contact Lenses are a type of contact lens that attempts to deliver the convenience of being able to see without eyeglasses all of the time. For many people the ability to get out of bed each morning and not have to insert their contact lenses is important. This is especially true if you are moderately or significantly nearsighted and can't even get to the bathroom without your glasses. For many people the thought of having to grope around the nightstand for their glasses in order to get out of bed is not a good feeling. Especially for a mother who must get out bed in the middle of the night to tend to a sick or crying child, or simply to get to the washroom.
For these people, as for almost anyone requiring optical correction of their vision, if the hassle can be eliminated, they are happier to choose that option. Extended Wear Contact Lenses may offer many people that option. Extended Wear Contact Lenses soft lenses are made from highly oxygen permeable hydrophilic polymeric materials. In general they are designed to allow for longer periods of time , from 7 to 30 days of continuous wear without removal,cleaning or disinfection. These lenses allow more oxygen to pass through to the cornea. An example of these types of lenses is Focus® NIGHT & DAY™ lenses which allow for 30 nights of continuous wear.
The more advanced technology Extended Wear Contact Lenses are made from silicone hydrogel materials that offer a number of advantages. First they allow up to 6 times more oxygen to pass through than even disposable contact lenses. In general they do not dry up as much as ordinary soft contact lenses which may be helpful to those with dry eyes who are trying to wear contact lenses. They have a special biocompatible surface treatment that decreases protein and bacteria buildup. This is important because protein and bacteria buildup on contact lenses predisposes you to eye infections. As with all Extended Wear Contact Lenses there is always a chance of affecting eye health even if there are no apparent problems. Although Extended Wear Contact Lenses may be very desirable because they allow you a great deal of convenience, they are by far the most risky type of contact lens you can wear
(http://www.fda.gov/fdac/features/1998/298_lens.html). If you are going to wear Extended Wear Contact Lenses you must always be under the regular care of an eye care practitioner and carefully follow their instructions.

They also neither fog when exposed to cold weather nor get splattered in the rain. Glasses on the other hand fog up and the wearer cannot see completely during rain pour.Contact lenses do not leave marks on the nose and are very comfortable to wear. No pressure is felt on the ears, temple, or nose unlike the glasses. Also glasses slide down from the nose during perspiration.As told before, contact lenses do not alter the appearance of the person.
Contact lenses offer adequate correction when the visual acuity of the eyes are more than 2.5 diopters, which is not possible with the glasses.

During the early years of contact lenses, it is but natural for people to feel discomfort wearing them. Not only were the contact lenses of old thick and unwieldy, the surfaces were solid and did not allow for air or moisture to circulate. Through technological developments, the days of chunky contact lenses are gone and most everybody can wear contact lenses without experiencing any form of discomfort.
Despite the advancements in the industry, there are still some people who experience adverse reactions to their contact lenses. They still have a slight sense of discomfort. These individual need not have to concede to spectacles or reading glasses. They can still wear contact lenses, they just have to find one that is suitable for them and Acuvue, the world’s leading contact lens brand has a product that may just be the answer these individuals are looking for.
Acuvue Advance is a kind of lens that provides users with a unique, soft and silky feel that lasts all day long. There is very little or no need for contact lens drops nor will you have to remove your lenses to give your eyes a rest. Acuvue Advance lenses are manufactured using Hydraclear, a breakthrough material that allows the lens to feel soft, wet and flexible the whole day through. The hydraclear material does not affect the ability of your Acuvue Lens to correct myopia (short / near sightedness) or hyperopia (long / far sightedness)
In addition to the unique hydraclear material composition, Acuvue Advance provides wearers with maximum UV protection. All Acuvue products, including Acuvue Advance, are treated to block out almost 98% of the sun’s harmful UV rays. Not only will you feel comfortable in your Acuvue Advance lenses, portions of your eyes will also be safe and protected.
Acuvue Advance Contact Lenses are considered as extended wear lenses. They can be used for seven days straight (without removing them for cleaning or disinfecting), or for a maximum of 14 days if you dutifully remove them at night and rinse or soak them in cleaning solutions.
Like all Acuvue products, Acuvue Advance has an inside-out mark which makes insertion of the lens in your eyes easier. In addition, Acuvue Advance lenses are tinged with a light blue hue. This colour does not, in any way, affect your eyesight but makes the lenses easier to see, especially if these are submerged in rinsing solutions.
Acuvue Advance can be purchased from any optical shop, pharmacy or even through the internet. Since Acuvue Advance is designed to correct visual problems, it is advised that you consult with an eye-care specialist or optometrist before you make any purchase, else you run the risk of experiencing more discomfort if you buy the wrong brand.
