Quick answer
During an eye test, an optometrist asks about your eyes and health, checks how clearly you see letters on a chart, finds your exact lens prescription with a series of lenses, and examines the health of your eyes, often including an eye pressure test and a look at the back of the eye.
The test is painless. Some practices use eye drops to widen the pupils for a fuller view of the retina, which can leave your vision blurry and light-sensitive for a while afterwards.
Step-by-step guidance
- Bring your current glasses or contact lenses, a list of medicines and your medical aid details.
- Answer questions about symptoms such as headaches, blurred vision or eye strain, and any family history of eye disease.
- Read letters on a chart for each eye, then compare lenses as the optometrist asks which is clearer.
- Have the health checks, which may include eye pressure, a microscope examination of the front of the eye and a view of the retina.
- Ask the optometrist to explain your prescription and whether any referral is needed.
What to check
- Whether your medical aid covers the eye test and lenses
- Whether dilating drops will be used, so you can arrange transport
- Your written prescription, which you are entitled to ask for
- The optometrist's HPCSA registration if you are unsure
Common mistakes to avoid
- Guessing on the lens comparison instead of saying when two look the same
- Driving straight after dilating drops while vision is blurred
- Not mentioning diabetes, high blood pressure or family eye disease
- Waiting years between tests because vision seems fine

No. Some tests involve a brief puff of air or eye drops, but none should be painful.
Can an eye test detect other health problems?
An eye examination can show signs linked to conditions such as diabetes and high blood pressure, and the optometrist will refer you if needed.
How often should I have my eyes tested?
