I have vertical double vision, which can only be partially corrected with glasses. When I look straight ahead or to the right I am fine but as I look to the left my double my increases from 3 deg to 10 and at the extreme left it is 20 deg. so when reading text my brain has a problem going from the right end of a line to the left end of the the line below. 88 was OK as the as the top blue band helped my brain. The bottom half of dbBenRoseySky is fine for me but the top half is hopeless. I struggle to read black on dark grey. Firefox Alpenglow would work for me, but the vertical stripes, particularly on the left throw my brain. Any suggestions would be gratefully received.
