Contact Lenses and your Eyecare Questions Answered Volume 3
Q. Will my eyes be continuously red?
A. If they are, something is wrong. Contact the fitter at once.
Q. Can you tell that someone is wearing contact lenses?
A. Usually not.
Q. Can they be coloured?
A. Yes. Lenses can be tinted almost any colour.
Q. Is that expensive? A. No.
Q. I’m worried about lenses slipping round behind my eyes. Does this often happen?
A. No, never, It’s impossible!
Q. I need glasses for reading only. Would I be suitable for contact lenses?
A. No. Stick to your glasses.
Q. I have astigmatism. Does this mean I can’t wear contact lenses?
A. Not at all. Hard lenses cover astigmatism. It is even possible to have special soft lenses for astigmatism.
Q. What is spectacle blur?
A. Temporarily blurred vision in glasses after wearing contact lenses.
Q. Is that serious?
A. No. Not unless very severe and persistent.
Q. What causes it?
A. Either a moulding of your corneas into a new shape, or a slight swelling from accumulation of fluid in the corneal outer layer.
Q. My friend wears very thin, hard lenses. Is that a good idea? A. The smaller the better, so long as they give good vision.
Q. She says she never gets spectacle blur. Why is that?
A. Very small lenses are less liable to cause this, because the corneas have a better oxygen supply.
Q. Why is oxygen important?
A. Corneas, like all living tissues, need oxygen to survive. As they can’t get it via the blood because they do not contain blood vessels, they have to get it direct from the atmosphere.
Q. What happens if I get a bit of grit behind a contact lens? A. You will know all about it. This doesn’t happen often.
Q. What should I do?
A. Take out the lens and wash it.
Q. But suppose the grit stays in my eye?
A. Get someone to remove it with the corner of a clean handkerchief, or see your doctor. Don’t use your lenses meantime.
Q. Is it very difficult to insert and remove contact lenses?
A. The difficulties in insertion are largely psychological. Removing lenses is easy, but it takes a bit of practice to learn todo it quickly.
Q. Is it a good idea to use a rubber sucker to remove lenses?
A. No. Not unless you can be certain that the lens is on the cornea.
