Should I shell out extra cash for disposable contact lenses? Many doctors highly recommend both disposable and frequent replacement contact lenses: they pose a lower health risk because there's less chance for protein and bacteria to build up on them.
Can I sleep in my contact lenses? It depends on the type of lens you're wearing, the composition of your tear film, your general eye health, and various other factors. Oxygen permeable contact lenses and certain soft lenses can be slept in, but always be sure to check with your eye care professional first.
Can I store contact lenses in tap water? No. Soft lenses must be stored in a disinfecting solution. Temporary storage in saline is allowed, but the lenses will have to be disinfected prior to the next use. RGP lenses can be stored in tap water in an emergency, but will need to be cleaned and conditioned by soaking in an appropriate disinfecting solution prior to use.
Can I lose a lens behind my eye? No. There is nowhere for it to go. The conjunctiva, the fine, thin membrane that covers the sclera (white part) and inside of your eyelids is well attached to the side walls of the eye socket. Although you can not lose a lens it can find its way up and under the upper lid and be pretty hard to locate. A soft lens can roll up and likewise be hard to find. Either way, if you flush your eye with water or saline, the lens should float out. In rare instances, a RGP lens may adhere by suction to the conjunctiva. First apply wetting solution to the lens and wait about a minute. Then try to move the lens while gently pressing on one edge. If that doesn't work, you can try to very gently lift up under one edge to break the seal. Or go see your eye doctor. If a contact lens adheres repeatedly, it is not fitted correctly and should be replaced.
How can I tell if I have the lens in the wrong eye? Alternately cover each eye with your hand. Do not simply squeeze your lids closed. Compare the vision. If one eye is noticeably better or worse, switch them and try again.
How can I tell if a soft lens is inside out? Here are three methods. Not all work for all lenses. (1) Place the lens on the tip of your finger facing upward, like a bowl. If when viewed from the side the edges of the bowl flare outward, it's inside out. (2) Add saline, drop by drop to fill the bowl. If the edges begin to curl inwards, it's the correct way. (3) Place the lens on the crease in your hand just below your pinkie. This is sometimes called the "life line or heart line". Make sure the lens is centered over the crease. As you curl your fingers inward to close your hand, the edges of the lens should roll inwards to form a "soft taco". This is the correct position.
My lens has a very small chip or tear in the edge but it doesn't bother me. Should I replace it anyway? Absolutely. Never, never wear a lens that is obviously damaged, even if it feels all right. It could be causing damage to your eyes that might not be immediately apparent. And never wear a lens which is uncomfortable, causes pain or leaves your vision hazy or distorted.
