You should have your eyes checked every year or two by an eye specialist. You may never know you have poor vision unless your eyes are tested.
If you need to wear glasses or contact lenses for driving, remember to:
Always wear them when you drive, even if you are only going a short distance. If your driver’s license or medical card says you must wear corrective lenses and you don’t, you could be placed out of service or receive a citation if stopped by law enforcement.
Try to keep an extra pair of glasses in your vehicle. Then if your regular glasses get broken or lost, you can still drive safely. This also can be helpful if you do not wear glasses all the time and you forget to take them with you when driving.
Don’t wear dark glasses or tinted contact lenses at night, even if it is to help with glare. The problem is that they shut out too much light -- light you need to see clearly.
