Thanks for the info. I've bought a new Vit E supplement that is only 100iu now, but am probably not going to take it until I can the veggie alginate.

I do think the vit e has helped my vision somewhat, which may be why I got the problem with my eyes in the dark, but I'll be happier with a lesser amount.

At the moment I'm just taking vit c, magnesium, zinc and folic acid.
