Night blindness (nyctalopia) treatment: Options to improve night vision
By: Devon Andre
Night blindness (nyctalopia) is impaired vision when the lights are dim or when it is dark. The condition is often caused by poor function of specific vision cells. Normally, our eyes quickly adjust to changes in the lighting, allowing us to still see. When this ability to adjust is impaired, it is known as night blindness.
Night blindness can be a result of various underlying conditions such as the degeneration of the rods (cells responsible for vision in dim light) in the retina, a vitamin A deficiency, or an inherited deficiency in visual purple (the pigment of the rods).
Night blindness can be scary and can even limit your abilities such as driving at night. Below you will find natural and medical ways you can try to improve your night blindness.
Natural treatment to improve night blindness
1. Wear red-tinted glasses
This is a common trick that aviators use when they don’t have time to sit in perfect darkness and adjust before night flying. Wearing red-tinted glasses before you go out into low light will help train your eye to focus better.
If you are looking at a map with a flashlight, cover the flashlight with a red-glazed paper. The red light will make the map appear sharper. And if you’re buying a new car, look for a dashboard with red illuminated buttons, rather than blue, green, or white.
2. Avoid looking directly at the light source
When you look directly at the light source, your pupils are forced to contract. This increases the amount of time it takes for your vision to acclimatize to the low light. If you can’t avoid looking at the light source, cover or close one eye until it passes.
Looking directly at light sources is a common concern while driving at night. If you are faced with oncoming high beams, protecting one eye will prevent you from getting flash blindness in both eyes (like a deer in headlights). Another trick while driving at night is to take your eyes off the oncoming high beams and look at the white line on your side of the road to maintain a safe course.
3. Let your eyes adjust to the darkness naturally
The best way to see in the dark is to let your eyes slowly acclimatize to low light. You can do this by sitting in perfect darkness 20 to 30 minutes before going out into the night. Or you can wear a sleep mask or just cover your eyes. This simple trick helps your eyes easily adjust to the darkness.
Special Forces use the technique of squeezing their eyes shut tightly for 10 seconds once they are in the dark……
