Extended Wear Contacts Over the last several years, there have been many improvements in contact lenses. As a whole, contacts are the best alternative to wearing glasses. They are comfortable, don t hang off your face, and above all - they are affordable. Among the many types of contact lenses available on the market, are the extended wear contacts. Doctors will tell you that when they don t monitor the fitting, usage of the contacts, and the overall effects, they may cause you serious problems and possibly even blindness. While a lot of people use non prescription contacts, few of them experience serious problems. When an individual buys non prescription contacts without going to see an optician, they tend to forget the fact that contacts aren t for everyone. You should also make sure that you dry your hands thoroughly with a clean towel, as soap residue or chemicals may get on the contacts, causing them to be very uncomfortable and possibly even burning your eyes when you put them in. If you can t seem to get your contacts to go in your eyes, you shouldn t force them. How To Clean Hard Contacts Hard, or rigid contacts are comprised of material that is known as PMMA (polymethylmethacrylate). 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. Most types of contacts need to be replaced every 2 weeks, and replaced with a fresh pair. If you are using daily disposable lenses, you should always throw them away before you go to sleep, then wake up to a fresh new pair in the morning. Another common mistake people make, that can easily damage or affect contacts, is swapping them with other people.
