Unlike other parts of your body, your eyes do not usually hurt when there is something wrong with them. Thus, regular eye examinations will reveal any conditions, which you may not even be aware of. Your eyes are one of your most important senses. If you experience problems with your eyes and sight, your whole life can be affected.
The eye examination can pick up early signs of potentially blinding eye conditions, such as glaucoma. If you have an eye condition, the earlier it is detected the greater the chance of successful treatment. An eye exam can detect health problems such as high blood pressure and diabetes.
There is obviously an important safety issue with good eyesight. Poor eyesight is particularly dangerous when driving and you must meet the legal requirement for driving.
