Alcohol is a drug. Alcohol alone, or combined with other drugs, and driving can be fatal. A vision examination is critical to safe driving. If you notice that your senior friend or relative is having trouble seeing, especially when driving, encourage him or her to have a comprehensive eye exam. Cataracts cause a film to cover the lens of the eye which then prevents light from entering the eye.

If this condition is not corrected, blindness can occur. Side vision is important because it helps you see movement or hazards on either side of your car while you are looking straight ahead. Their eyes are more sensitive to bright light and it takes longer for their eyes to adjust when they are in bright sunlight or at night because of headlight glare.
