Primarygun Posted April 21, 2005 Share Posted April 21, 2005 We can obtain Vitamin A from many kinds of food, such as liver, green vegetables. It helps form purple visual pigment of the rod cells of our retina and prevent us from suffering from night blindness. If we lack vitamin A, does it lead to blindness?

Green Posted April 25, 2005 Share Posted April 25, 2005 It will not lead to complete blindness but could lead to inability to see in dim light., Link to comment Share on other sites More sharing options...
Skye Posted April 25, 2005 Share Posted April 25, 2005 Green, what you're saying flies in the face of what is normally written about vitamins. Is there any reason for that? Link to comment Share on other sites More sharing options...

Mokele Posted April 29, 2005 Share Posted April 29, 2005 Maybe vitamin A doesn't cause total blindness simply because the other effects of vit A deficiency will kill you first? Mokele Link to comment Share on other sites More sharing options...
