Most individuals take about 20 minutes to see adequately in the dark. This time allows your eyes to adjust from the brightness of daylight or indoor lights to the dark. However, some people simply cannot adjust to seeing in the dark. These individuals have a condition called night blindness, and it’s very common especially as we age.
In the natural aging process, the eye lens becomes less clear and grows cloudy over time making it difficult to see in dim light. The condition known as night blindness is not a true blindness, but rather a dimming of vision so that everything seems hazy and hard to see.
When you begin experiencing night vision problems you should consult with your physician to make sure you don’t have a disease related condition. However, if it’s just age working against you there are some measures you can take to help improve your night vision:
- Keep your glasses clean if you wear them, and this includes sunglasses. Having dirt on the inside or outside of your lense can disturb the filtering of light and scatter it, making it more difficult to see and increasing an already existing vision problem.
- Keep your car windshield clean. Make sure you wash the inside and the outside of your car windows. Having dirt and debris on your windshield makes it harder to see, especially at night when there isn’t much light. Having a dirty windshield can have the same effect as having dirty eyeglasses.
- Avoid looking at oncoming car lights head-on. If you look to the side of the lights, you will not experience the glare that occurs when you look at them dead on. Oncoming headlights can dim your vision by their own brightness, and looking to the side helps to minimize this effect.
- Eat Vitamin A rich foods. Foods containing beta-carotene help you to see better in dim light. So, consume cantaloupe, carrots, collard greens, kale, and chicken often and you won’t be nutritionally deficient in Vitamin A which helps you see better overall. However, don’t overdose on Vitamin A supplements or foods because having more than you need doesn’t help you see any better than merely getting the proper amount.
