Gas Permeable Contact Lenses Also known as oxygen permeable contacts, gas permeable contact lenses are a lot easier to take care of then other types of contacts - including soft contact lenses. GP (Gas Permeable) contacts are made from a combination of fluorine and silicone, meaning that they won t attract protein near as much as other types of contacts. This material is very rigid, and doesn t contain near as much water as soft contacts. With that in mind, taking care of and cleaning hard lenses is very different that cleaning and maintaining soft contact lenses. Before you purchase a pair of hard or rigid contacts, you should know how to take care of them and how to clean them. When you are ready to take them out, look up with your eye then use your fingers to grab the contact by the sides and pull it out. You can normally get it out on the first try, with a little practice. Once the contact is out, blink a few times to clear your eyes. If it doesn t want to come out, put some drops in your eye to moisten it up, then try again. There is no need to worry about anything with these lenses, for the simple fact that you ll get a pair for each new day. Unlike the traditional contact lenses, 1 day contacts are an ideal way to protect your eyes and still get the vision you need to carry out your day to day activities. Acuvue 1 day lenses are also the only contacts in the world that offer you daily usage with complete UV protection. Although other types of Acuvue lenses now offer Hydroclear, the advance lenses were the first. Hydraclear is a break through in contact lens technology, perfect for those who have problems with their lenses drying out. This technology is considered to be among the best - and ideal for anyone who wants the best for their eyes. Contact lenses, as we all know, have many different uses. They are mainly used to correct vision, although they can also be used for those who have just had cataracts, especially if the natural lens around was removed. Contacts can also be used in the treatment of various eye diseases, and scars on the cornea that have been caused by infections or injury.
