Top 5 questions asked about an eye test
1) My child really wants spectacles – how will the eye care practitioner know if they really need them or not?
During the eye test, the practitioner can use different types of instruments and tests to check if a spectacle prescription is required. These are called objective tests, such as an auto refractor, which is an electronic device and also a retinoscope, where by shining light into the patient’s eyes, the practitioner can calculate the prescription. Both of these instruments are helpful when a patient might not be so co-operative.
2) I have astigmatism. What is it, and how can it be corrected?
Astigmatism means that the shape of the eye is not entirely round, but more oval in shape. This causes blurred vision both for distance and near work. It can be corrected with spectacles and contact lenses for astigmatism.
3) How often should I be having an eye test? I can see perfectly well. Why do I need an eye test?
Children should have their eye checked at least once a year, and adults every two years. However, with some other conditions such as diabetes or if there is a family history of any eye problems, then more frequent eye tests are advisable. Your eye care practitioner will guide you accordingly.Due to the fact that certain eye conditions such as glaucoma do not always hinder your vision initially, it is important to check and ensure that your eyes are healthy even if you can see well.
4) I want to try contact lenses, but don’t know what to do?
You can have a contact lens fitting trial, where the practitioner will assess if you are suitable for lenses. They will fit some lenses into your eyes and they will teach you how to insert, remove and care for the lenses.
5) If I wear spectacles will my eyesight get worse?
Absolutely not. In fact quite the opposite. Research and studies on short sightedness carried out in the past few years are showing that children should be given spectacles as soon as they need them and their spectacle prescription should be updated regularly to try and reduce the increase in their lens power. Where necessary, children who are longsighted should also be given spectacles to prevent the possibility of getting amblyopia (lazy eye).
As regards adults, not wearing spectacles when needed can cause eyestrain, fatigue and headaches.
