14. Compensation for Poor Vision

A person can compensate for poor visual acuity by wearing glasses or contact lenses prescribed by a ophthalmologist or optometrist.

A person can compensate for poor depth perception by using extra caution in judging the speed and distance of oncoming vehicles and approaching objects.

A person can compensate for poor peripheral vision by frequently turning the head to increase his or her field of vision.

A person can compensate for poor glare resistance and recovery while driving by using the sun visor, wearing sun glasses or other dark lenses during the sunset, and by avoiding looking into the headlights of oncoming cars.

A person can compensate for color blindness while driving by learning the general shapes and patterns of signs, and relying on the position of signal lights, rather than on their color.

If you wear glasses...

Whenever you drive, you must wear the glasses or contact lenses that have been prescribed for you or are required by a restriction on your license.

You should never wear dark glasses at night and you should consult a physician regarding the safety of wearing tinted contacts at night.

You should not wear glasses whose frames or lenses obstruct your peripheral vision.

Aging and vision

Certain aspects of vision deteriorate slowly with age, sometimes so slowly that people do not notice the change. It is important to have your eyes checked every year or two by an optometrist or ophthalmologist to ensure that you are not putting yourself or others at risk while driving.
