How to Optimize Night Vision

Even those with adequate vision during the day can struggle with night vision. A decline in vision, especially at night, often happens due to aging. Eyes can take in and interpret a wide variety of light intensity, from bright sunlight to the dim light from the moon. In one form of night vision, you may not see colors -- just outlines of gray. Instead of being able to see intricate details, you may not be able to make out any details of what you're seeing, or you may not be able to estimate the size of -- or make out details of -- items at great distance. Learn how to optimize night vision for safety.

  Stay out of the sun or bright lights during the day. If you know that you'll be outside during the evening, stay inside as much as possible during the daytime. Another option is to wear sunglasses as much as possible during the day.

  Avoid looking into headlights. If you're driving at night, averting your eyes from oncoming headlights will optimize night vision. Don't actually move your head to the side, which can be dangerous. Just focus your eyes on the road or above or below the headlights.

  Look at objects slightly off-center while in the dark. If you look directly at an object and try to focus, it will not be a clear image. Look slightly sideways, and it's easier to focus.

  Have an anti-reflective coating put onto your prescription glasses. Another option is to buy special glasses suitable for night vision. The lenses of these glasses have a diagnostic technology that reduces glare and other distractions. The anti-reflective coating cuts the glare, which is especially helpful when driving.
