Frequently Asked Questions
What happens in an eye examination?
Many things are investigated during an eye exam (which typically lasts about 25 minutes). Firstly, the vision will be checked and lenses put up if necessary to improve the vision. The health of the eye both front and back will be thoroughly investigated. The eyes will be checked for squints, cataracts, and the presence of glaucoma. Visual field tests and other auxiliary tests will be carried out if need be.
How often should I have a sight-test?
It is recommended that everyone should get their sight checked at least every 2 years. Even for those who feel they have perfect sight it is important that regular checks of the ocular health be maintained to avoid any potential problems in the future (e.g. glaucoma). Your eye specialist will advise if more frequent check-ups are needed (e.g. people with diabetes).
What is myopia (short-sightedness)?
If a person is having problems seeing objects at a distance but can see things up close clearly, they are generally considered to be myopic. This can often become a problem during adolescence and is easily corrected with spectacles or contact lenses.
What is hyperopia (long-sightedness)?
If a person has problems seeing things up close but feels more comfortable focussing on distant objects, they are considered to be hyperopic. Again, correction is generally achieved using spectacles or contact lenses.
What is astigmatism?
Astigmatism is a condition where the eye is oval in shape rather than round (the front of the eye is like the shape of a rugby ball rather than a football). It is an extremely common condition and can be associated with being either myopic, hyperopic or both. Spectacles or contact lenses can be used to rectify this.
Why am I having problems reading?
Most people that have sharp vision throughout their life and don’t wear glasses will start to experience problems focussing on close print when they reach a certain age (normally mid-forties). This condition is known as presbyopia and is perfectly normal. The lens within the eye becomes less flexible and cannot focus on close objects effectively. Spectacles need to be supplied to correct this.
