Years ago, glasses that contained bifocal lenses were just about the only option available. Over the years, no-line lenses were created, and glasses became a bit more attractive. This was a very definitive time for bifocal correction lenses, as they looked a lot better than they ever did in the past - eliminating the bulky and unattractive appearance they were well known for. Simply place a few drops of the cleaner in the center of your hand and then rub the lens gently in the solution. You should rub the contact around for about 30 seconds, ensuring that you clean both sides. When you need to rinse and disinfect them, simply use other products that are designed for that purpose. The first thing to do when cleaning your hard contacts is to take the lens out of your eye and put it in the center of your hand. You should have your cleaner out, and ready to use anytime you are looking to clean your lenses. Once you have the lens in the palm of your hand, squirt a couple of cleaning drops into the center of the lens. Contact Lenses Without A Prescription Even though you can get non prescription contacts, they aren t meant to correct your vision. Known as plano, the most common type of non prescription contact lenses are the opaque color contact lenses. Even though they don t require a prescription, those who want them need to consult with an optometrist first to ensure they get the right fit. In order for your optician to give you a prescription for contact lenses, your cornea will need to be free of any type of problems that can prevent you from wearing them. Normally, your optician will give you a trial pair of contact lenses to try out, and then check them for fit once they have settled in your eyes. All in all, contact lenses are preferred over glasses. You ll need to change them out though, normally every couple of weeks. Changing them out with a fresh pair will make your eyes feel refreshed, and keep you from getting infections. Contact lenses are great for virtually anyone, and they can give you a full range of sight.
