Symptoms, conditions and causes

Why do I have poor night vision?

Poor night vision means it’s hard to see during the night or when it is dark. Let’s look at the root cause behind it.


  • Can’t see at night

  • Disoriented when it’s dark outside

Cause #1: Vitamin A deficiency

One of the functions of vitamin A is to sensitize the cells in the eye to respond to light. Without vitamin A you will not be able to see at night. The active form of vitamin A is called retinol. Retinol is found mainly in animal products. If consuming vitamin A-rich foods doesn’t remedy the situation I suggest improving the absorption of it by assisting the liver with the production of bile (absorbs vitamin A).


  • Consume grass-fed meats

  • Consume a vitamin A supplement

  • Consume purified bile salts to improve the digestion of vitamin A
