[Nfb-krafters-korner] lighting

[River Woman]

Light is not my friend.
I am very light sensitive, and have light perception and some peripheral 
vision.
I have to have several different kinds of shades to wear accorsding to the 
light conditions.  I have to change them for each different light condition, 
so that means I carry a big handbag to hold at least 3 different kinds of 
glasses.
