People need to have a regular eye check-up at least every 2 years. Diseases like glaucoma are very hard to diagnose yourself, as there aren’t always obvious symptoms. Only an eye pressure test will be able to tell us your eyes’ health condition. For example, with glaucoma your nerves can deteriorate without your knowledge, subtly and gradually affecting your peripheral vision.

If you have diabetes (not every knows they have the disease), only by looking at the back of the eye will we be able to know for sure if high blood sugar levels over prolonged periods have caused mini-haemorrhages. This is the only time one can see the blood vessels clearly.
