If my vision's fine, do I need a regular eye test?
Yes. A comprehensive sight test includes checking the health of the inner and outer parts of the eye.
Even if you're happy with your vision it's worth having a regular check-up. Eyes can be affected by a number of conditions which may be picked up early through a sight test, giving it less chance of affecting your vision.
You should have an eye examination every two years or more regularly if advised by your optometrist.
