Answer: A basic eye test should include an external examination as well as tests for visual acuity, pupil function and ocular motility which each provide pointers to potential eye health issues. The External Examination involves a check of your eyelids as well as the tissues around your eyes to check overall eye health. Visual Acuity tests are where your actual vision and ability to see details is tested. This will determine your prescription and show severe vision problems. Pupil Function tests are designed to see that your pupils are the same size and react predictably to light exposure. Issues with pupil function can point to a variety of different defects or problems which can be addressed once diagnosed. The Ocular Motility test shows how quickly the eye can move around and is often performed with a series of simple gestures performed by the optician. Poor motility can result in issues with reading and similar skills, which is why diagnosis early in life can help to address potential learning difficulties.
Question: At what age should I start getting my eyes tested?
Answer: You should start having eye tests before you begin school. Your parents should take you for at least one eye test before you begin school so that if you have any vision problems, they can be remedied before they cause lasting educational issues. Very few people realise how difficult learning can be for a young child with an undiagnosed sight problem. After your first eye test, it is advisable that you get your eyes tested every year to two years. It will allow any sight problems to be detected early and addressed as quickly as possible.
Question: Why does the optician need to know about my lifestyle before the test?
Answer: The optician needs to know if there are any environmental factors to be aware of when performing your sight test. It also means that they can be on the lookout for any specific abnormalities that they might not typically test for. A prime example is whether you look at a screen for hours a day, whether for work or leisure. Glaucoma is another factor that can be tested for if you make your optician aware that you have a predisposition to it, due to family history or due to age. Detecting glaucoma requires a particular battery of tests that are not all performed as routine so highlighting that risk can ensure that your eyes are thoroughly tested for it. Early detection can help you tackle the problem early and potentially avoid serious damage to the optic nerve.
