How many people have reduced vision at night, or can't see very well in low-light environments? If you have similar symptoms, be on the lookout for night blindness.

Night blindness is usually caused by a lack of vitamin A. Dark adaptation is mainly the role of rod cells on the omentum, and the synthesis and metabolism of rod cells requires the participation of vitamin A, so vitamin A supplementation has also become the most important way to treat night blindness.

In the various herbal extracts, the most commonly used ingredients for night blindness are vitamin A and lutein, of which lutein is the main pigment present in the macular area of the human retina, and the macular area is affected by blue light and will lead to free radicals increase, resulting in an increase in metabolic waste. Lutein is safe and harmless. As a powerful antioxidant, it is usually taken in combination with vitamin A. Vitamin A helps improve dark adaptation. Lutein helps protect the eyes from UV rays and blue light, reduce eye aging and prevent macular degeneration.

In addition, eating more eggs, liver, crucian carp, carrots etc. in the daily diet will also improve eyesight.
