If you can’t see anything in the dark, it could be THIS

There is a condition called “night blindness” that is experienced by many people around the world (yes you are not alone, even if you can’t see anybody else). However, this does not mean that they are completely unable to see anything at night. It just means that they have poor vision in dimly-lighted conditions or at night. Most of them are still able to see vague and blurry outlines.

There are many causes and reasons for this condition, and they may vary according to people.

For example, cataracts could be the cause of night-blindness. Cataracts are the result of cell-turnover in the eye, so basically, dead cells pile up in the eye over its life time. This of course results in impaired vision and hence, night blindness.

However, a much more common reason would be nutrient deficiency. Vitamin A is essential for healthy retinas. If you don’t eat enough carrots or green vegetables, you may be lacking in Vitamin A. However, if your diet is perfectly fine, it could also be due to your body’s inability to absorb the nutrients. In that case, you should probably check for diseases such as celiac disease, cystic fibrosis, etc.

Zinc is also required in conjunction with Vitamin A to ensure healthy eyes. Having one and not the other nutrient will still result in night blindness.

Lastly, illnesses can also result in poor night vision. Retinitis Pigmentosa is a rare genetic disorder that can affect the eyesight of young people below 30. The first symptom that appears is usually worsening night vision. Diabetes can also cause poor night vision, as the high sugar levels in the blood stream can affect nerves in the eye.
