FREQUENTLY ASKED QUESTIONS
Q: Is it true that wearing glasses all the time will make my
eyes lazy and I will become dependent on them?
A: No. When people wear the proper glasses they realize they
can see more clearly and comfortably. What they may have
considered normal and acceptable before is now inferior by
Q: Is an optometrist the same as an optician?
A: The term ‘optometrist’ came into use in 1987 to replace
‘ophthalmic optician’ in the same way that ‘pharmacist’ replaced
‘chemist’. An optician can be ophthalmic, dispensing or
manufacturing; it is the optometrist who is qualified to test your
eyes. Some dispensing opticians have extra qualifications that
enable them to fit contact lenses and carry out certain clinical
Q: I’m diabetic. Does that make a difference?
A: Yes. Diabetes can cause severe problems with your sight. It is
very important that your eyes are checked every year, preferably
with drops to dilate the pupil, so that the retina (back of the eye)
can be examined thoroughly.
Q: How old does a child have to be before he or she can
have an eye examination?
A: Any age really. A child’s eyes have finished developing by the
time they are about eight years old. Many health authorities
screen children in their area at around three years of age, but if
you are concerned, or if there are any members of your family
with eye problems, then it’s best to have your child’s eyes tested.
Q: Are paper tissues alright for cleaning my glasses with?
A: If you have plastic lenses in your glasses then dry tissues will
scratch them. It is generally better to dampen the tissue, or even
use soapy water and a soft cloth. Glasses with anti-glare coatings
should be cleaned with a special cloth and spray.
Q: How long should a sight test take?
A: It depends on who the patient is. A young, healthy person with
no apparent problems will take about 20 minutes. Someone older,
perhaps with high blood pressure, diabetes, glaucoma or other
ailments can take much longer. The optometrist will determine
what clinical tests are needed to provide the correct information
for new glasses or contact lenses. If necessary, they may refer
the patient for a medical opinion.
Q: I think I have good sight, but I would like to have glasses
as a fashion accessory. Would an optician be prepared to
give me glasses that don’t change my vision?
A: If you’ve had your eyes checked and they are as good as you
think, then your practitioner will have no objection to you having
plain or tinted lenses in a frame of your choice, or contact lenses
that can enhance or change the color of your eyes.
Q: If there is a history of glaucoma in my family, am I likely
to inherit it?
A: If there is glaucoma in the family, you may be more at risk of
developing it. Glaucoma can be treated effectively if it is
diagnosed in time, so be sure to have a regular eye examination.
Q: What are cataracts?
A: A cataract is when the lens inside the eye gets cloudy
preventing you from seeing clearly. It is not a curtain or film that
grows over the eye. Cataracts develop to a greater or lesser
extent in many people as they get older, but often don’t affect
people’s eyesight severely, if at all.
Q: Can I sleep in my contact lenses?
A: No, unless specifically told that you can by your eyecare
practitioner. Sleeping in your lenses can be hazardous as it can
lead to infection or damage to the cornea (front window of the
Q: Does it matter what contact lens solution I use?
A: It is important that you follow the advice of your practitioner.
Not every solution will suit every patient, for the lenses they are
wearing. If you do change your cleaning system for any reason,
always inform your practitioner.
Q: I’ve been told that I can’t wear contact lenses because I
have astigmatism. Is this true?
A: There are many kinds of contact lenses available now which
will correct astigmatism, both in soft and gas permeable materials.
Your practitioner may be able to fit you or may recommend a
colleague if it is a specialist fitting.
Q: I’ve heard that contact lenses can slip round to the back
of my eye. Is this true?
A: No. There is a thin, transparent membrane which covers the
inside of the eyelids and the outside of the eye. This forms a seal
which prevents contact lenses – as well as grit, dust and other
‘foreign’ material – passing round to the back of the eye. It has
been known for contact lenses to ‘hide’ beneath eyelids, but this
is easily rectified.
