how can we prevent night blindness?
Answers
Here is your answer
Explanation:
Your eye doctor will take a detailed medical history and examine your eyes to diagnose night blindness. You may also need to give a blood sample. Blood testing can measure your vitamin A and glucose levels.
Night blindness caused by nearsightedness, cataracts, or vitamin A deficiency is treatable. Corrective lenses, such as eyeglasses or contacts, can improve nearsighted vision both during the day and at night.
Let your doctor know if you still have trouble seeing in dim light even with corrective lenses.
Cataracts
Clouded portions of your eye’s lens are known as cataracts.
Cataracts can be removed through surgery. Your surgeon will replace your cloudy lens with a clear, artificial lens. Your night blindness will improve significantly after surgery if this is the underlying cause.
Vitamin A deficiency
If your vitamin A levels are low, your doctor might recommend vitamin supplements. Take the supplements exactly as directed.
Most people don’t have vitamin A deficiency because they have access to proper nutrition.
Genetic conditions
Genetic conditions that cause night blindness, such as retinitis pigmentosa, aren’t treatable. The gene that causes pigment to build up in the retina doesn’t respond to corrective lenses or surgery.
People who have this form of night blindness should avoid driving at night.
You can’t prevent night blindness that’s the result of birth defects or genetic conditions, such as Usher syndrome. You can, however, properly monitor your blood sugar levels and eat a balanced diet to make night blindness less likely.
Eat foods rich in antioxidants, vitamins, and minerals, which may help prevent cataracts. Also, choose foods that contain high levels of vitamin A to reduce your risk of night blindness.
Certain orange-colored foods are excellent sources of vitamin A.
