E50.5: Vitamin A deficiency with night blindness
Vitamin A is important for vision along with the skin and mucous membranes. Furthermore, you need vitamin A to regenerate particular cells such as blood cells. You can obtain vitamin A through various foods like liver, fish and green vegetables.
A vitamin A deficiency can develop when you are taking too little vitamin A via food. It is also possible that your intestines aren’t able to properly absorb vitamin A into your body because of another disease.
When it is dark, the eye adjusts to the altered lighting conditions. With a vitamin A deficiency, this adjustment no longer works correctly.
