Hard contact lenses are made of a material called polymethylmethacrylate (PMMA). It is rigid and unlike soft contact lenses, does not contain much water. For this reason the cleaning and upkeep of hard contact lenses differs somewhat from that of their soft counterparts.
Upon purchasing a pair of hard lenses, it is important to be sure that as the wearer, you have an extremely good understanding of how to care for your hard lenses. High on your list of priorities should be your choice of hard contact lens cleaner.
It goes without saying that before handling your hard lenses you must wash your hands thoroughly with soap. An antibacterial soap is the most appropriate choice but any will do just as long as it doesn’t contain fragrance.
Next step is to remove the lens from your eye with utmost care and gingerly put it in the center of your hand. Now it’s time to get out your hard contact lens cleaner. Take the lens cleaner and apply approximately two to four drops (depending on how dirty it is) to the lens. In a delicate manner work the solution into the hard lens for a period of around thirty seconds. Don’t overdo it or you could tear the lens.
Now it’s time for the rinsing stage. Rinse your hard lens with ordinary lukewarm water from the tap. Hard contact lenses are sturdy and require nothing special for this step. Once you are satisfied that no residue from the hard contact lens cleaner remains on the lens, put it back in its special lens case and proceed to fill it with conditioning solution specifically made for hard contact lenses. Then repeat the exact same procedure with the other eye.
