Your eye examination explained:
An eye examination reveals far more than whether you need spectacles or a change in spectacle prescription. It also involves a range of tests to assess the health of your eyes. Many eye diseases and general health problems such as diabetes and raised blood pressure can be detected during a routine eye examination. The eye examination may include the following elements and other tests where appropriate.
History and symptoms
We will ask a range of questions to determine if you have any problems with your eyesight and general health. Some medications can affect the eyes and many eye conditions are health-related so we ask if you are taking any medicines. We also like to know about family eye problems as some eye diseases are hereditary.
If you already wear spectacles or contact lenses, you should bring these to your appointment. We will then check the lenses to determine your current spectacle prescription and the type of lenses you are wearing.
This part of the examination finds out whether you need an optical prescription and if so, the strength of lens needed to give you the best vision. We check your distance and near vision and perform several tests which ask you to compare differing levels of clarity with various lenses we show you. These tests show what type of sight defect you may have and allow us to prescribe an appropriate spectacle prescription.
These tests check that your eye muscles work together to ensure maximum visual comfort.
The pupil controls the amount of light reaching the retina at the back of your eye. An unusual pupil reflex can sometimes be caused by neurological problems.
This test measures the pressure inside your eyes. If the pressure is too high you may develop glaucoma, a disease which eventually leads to blindness if untreated. The test is usually carried out on people over 40 or those with glaucoma in the family. It is a painless test and may involve an instrument blowing a puff of air onto your eye or anaesthetic eye drops and application of a small probe onto the eye surface.
Visual field test
This test checks your all-round vision and can detect glaucoma and some neurological conditions.
Slit lamp/Retinal photography
These are very important parts of your examination because they check the health of your eyes. These instruments enable us to see your retina, macula, optic nerve and blood vessels. This enables us to check for problems such as cataracts, glaucoma and macular degeneration as well as signs of conditions like diabetes and hypertension.
After your eye examination you will be given a full explanation of our findings and we will be happy to take the time to answer any questions you may have.
