Poor night vision is the effect of changes in the pupil, lens and retina. Different methods used for night vision improvement may not work out well for everyone; however, there are techniques that are doable. Eye exams are recommended as one may have slight astigmatism which makes it harder for eyes to adapt to darkness. Eating the right foods that are rich in vitamin A and taking supplements can help poor night vision.
In addition to the regular eye changes that individuals of all ages may encounter, it’s been said that one of the main causes of diminished night vision is an aging eye. The iris consists of a set of muscles that control the size of the pupil. Muscles in the iris get weaker and less responsive with age. A smaller pupil means lesser light entering the eye makes it harder for adjustable changes encountered from light to darkness. Normal rod cells contained in the eye do play a major role in the ability to see in the dark especially after being exposed to bright light. Dark adaptation does not regenerate fast enough when the rod cells lessen.
Vitamin A does protect the surface of the eye and is essential for good vision. Consuming foods that are rich in vitamin A will improve your vision at night. Foods rich in vitamin A include the following: Carrots, broccoli, kale, sweet potatoes, pumpkin, collard greens and cantaloupe. Regular in take of multivitamin supplements is highly recommended. Practice usage of the peripheral vision can improve vision. By using the peripheral vision one uses more rod cells that are required for proper night vision.
Exposure to bright light does reduce the ability to adjust to darkness. Wearing glasses with a neutral, gray tint is recommended. Finding proper means of covering the eyes for a few minutes after being exposed to bright light will make considerable difference. It has been noted that 2 to 3 hours of exposure to bright light can reduce the ability to adjust to darkness by 10 minutes. Some individuals find that closing both eyes tightly and applying slight pressure with the palms for a few seconds works well with any adjustments. Since light sources diminish night vision, avoid looking directly at light sources while navigating in the dark. For example, if driving at night and someone comes around the bend with high-beams on, protecting one eye by covering it with the palm will prevent “flash blindness” and allow easy adjustment to the darkness.
