i don't remember the name of it, but in one of david wolfe's videos he demonstrates a very inexpensive little pad that you just touch to ground out. i think it is hooked up to a real ground in the earth. or you can just walk barefoot on earth.

for glare, just turn your lights down, use shades or get full spectrum light bulbs.
