You can often underestimate how important a regular eye examination is. Everyday situations such as using a computer, watching television and driving can all put a strain on your eyes so it is important to have a regular check-up. An eye test can help detect eye conditions like long or short sightedness and eye disease before you notice the effect on your sight. Below 40 years of age, we recommend that you have a sight test at least every 2 years. Above 40 or if there is any history of eye disease in your family, you should have a test every year.
