Contact Lens Frequently Asked Questions We have put together a list of the most common questions received by our doctors and staff. -Can I wear soft contact lenses if I have astigmatism? Yes, you can wear a special type of soft contact lens called a toric lens which will correct your astigmatism. However, these lenses are typically more expensive and there are fewer types available than there are with regular (spherical) lenses. Some of the more popular disposable toric lenses include the Acuvue Advance For Astigmatism , the Purevision Toric and the Proclear Toric . Several manufacturers including Ciba (Focus) and Coopervision (Preference) produce 1-3 month frequent replacement toric lenses. -Can I wear soft contact lenses if I need bifocals? Yes, there are a number of contact lenses designed for people who need bifocal (multifocal) correction. Some of the more popular disposable toric lenses include the Acuvue Bifocal , the Purevision Multifocal and the Proclear Multifocal . -Is a contact lens prescription different than a glasses prescription? Yes. When you order contact lenses, you must have a current contact lens prescription which specifies the power of the lenses, the size of the lens, the type and brand of lens. See also How to Read a Contact Lens Prescription. -If my 2 week disposable lenses are still comfortable and in good condition beyond 2 weeks, can I continue to wear the same pair? In order to maintain optimal eye health and comfort, it is important to adhere to the wearing schedule prescribed by your doctor. The main advantage of wearing disposable lenses is that you are putting a fresh new pair of lenses in your eyes every 2 weeks. Also, the convenient cleaning regimen of a disposable lens is only adequate for a 2 week wearing schedule. -If I only wear my 2 week disposable contacts part time, do I still have to replace them every 2 weeks? No, the 2 weeks refers to the actual amount of wearing time so they can last longer than 2 weeks if you are not wearing them full time. -Your website lists my lens as 2 week disposable, but my doctor says I can wear them for 4 weeks. Which is correct? The lens wearing schedules on our website are provided by contact lens manufacturers. However, doctors may decide on a different wearing schedule (shorter or longer) for an individual patient based on wearing habits, lifestyle, cleaning methods etc. You should always follow the wearing schedule prescribed by your doctor. -What's the difference between rigid gas permeable (RGP) lenses and soft lenses? RGPs are smaller and made out of a harder, less pliable material than soft lenses which makes them less comfortable initially. RGPs correct some astigmatism whereas soft spherical lenses do not. -Can I swim with my contact lenses in? It is best if you don't because there are bacteria in the water that can adhere to your lenses and cause infections. If you do swim in your lenses, you should wear goggles over them and you should disinfect them immediately afterwards.
