Have your eyes tested periodically. Your visual acuity and visual field tend to decrease as you age. Make sure your windshield is clean and your wipers effective. You can help yourself by ensuring an unobstructed view. Clean the lenses of your headlights periodically.
Dirty lenses can decrease illumination dramatically.
Not only will you see better at night, but other drivers will see you better. As people age, their ability to recover from glare decreases. If you must drive at night, give yourself enough time for your eyes to adjust to decreased light. If you can, avoid left lane driving. When confronting oncoming traffic, try not to look directly at it.
