. I have dry eye problems. Can I wear contact lenses?
You’re less likely to have success with contact lenses than someone who does not have this condition. This does not mean that you cannot wear contact lenses at all. It simply means you may have a shorter contact lens wearing period than normal or that you may choose to wear your lenses only occasionally. You can increase the comfort of your lenses by inserting eye lubrication drops. As always, it is best to consult your eye care practitioner for the best advice regarding whether you should wear contact lenses and what type of lenses may be suitable.
Biocompatibles' Proclear lens has been designed specifically for marginally dry eye problems.
My doctor told me I couldn't wear regular contact lenses for presbyopia. Why not?
Presbyopia is a vision condition in which the eye cannot focus on near objects. In most cases, reading glasses or bifocal glasses are prescribed to correct presbyopia. But contact lenses can be prescribed also. Special bifocal contact lenses are available, such as the Acuvue Bifocal. As an alternative, many practitioners prescribe a system called monovision where one eye is fitted with a distance lens and the other with a reading lens. Approximately two-thirds of patients adapt to this type of contact lens wear, with the brain automatically switching to the eye more clearly in focus.
Wearing contact lenses while traveling by plane can be uncomfortable. Why, and what can be done to lessen the discomfort?
The low humidity in aircraft cabins contributes to dry eye symptoms and contact lens discomfort. It may help to put lubrication drops in your eyes before you enter the airplane or during flight. If symptoms persist or become severe, it is probably easiest and best to wear eyeglasses when flying.
Can contact lenses be "blinked" out?
With normal use, contact lenses will stay firmly in position. However, they can come out under certain conditions. High winds can cause the eyes to water and pull the eyelid tight against the eye, increasing the chance of lens loss. A sharp blow to the head may dislodge rigid gas permeable lenses. And rubbing your eye carelessly may result in a lost lens. Describe to your eye care practitioner all of the circumstances in which you are likely to wear your contact lenses. This will help him or her prescribe a type of lens that is less likely to be dislodged given your activities.
Is it OK to swim while wearing contact lenses?
Only if you’re wearing goggles with a firm seal. If you don’t wear goggles, the contact lenses may float from your eyes and/or they will absorb the pool water, one consequence of which may be that they adhere quite firmly to the eye. If this occurs, it is advisable to leave the lenses alone for 10-15 minutes until the water in them has been replaced by natural tears before trying to remove them. Exposing your contacts to pool water also places you at risk of discomfort due to chlorine and infection from bacteria or other microorganisms.
Can my contact lens be "lost" behind my eye?
No, a thin, but strong, membrane, called the conjunctiva, lines the inside of your eyelids and curls back on itself to cover the white part of the eye. Lenses cannot pass through it. However, your contact lenses may slide under your eyelids or become displaced. If this occurs, try looking in the direction of the lens to get it to move back to the correct position. If you wear soft contact lenses, they will tend to center automatically on the cornea. If you wear rigid gas permeable lenses, you may need to manipulate a displaced lens through the eyelid.
