Everyone should have a sight test every two years, or more often if your optometrist recommends it. As well as an eye health check, a sight test might detect signs of underlying general health conditions, such as diabetes, high cholesterol and high blood pressure.
Within your sight test, the optometrist will check both your ability to see close up and in the distance and will then work out whether there is a need for glasses and a change in prescription with a series of tests using different lenses.
History and Symptoms
The optometrists will ask detailed questions about your eyesight, lifestyle health and any previous eye problems you or family members may have had. You should bring a list of any medication you take, along with your glasses if you use them, or a previous glasses prescription.
