I woule also like to upgrade my adult macular degeneration which has robbed me of my right (dominant) eye sight and depth perception. Brian's Salvador Dali one eyed squint is close to my situation, particularly when rigging and trying to grasp a small line with my tweezers and not grasping it as i don't know if the tweezers are infront or behind . . . . so I raise up my magnifiers, back off and look to where my hands are actually placed. Enjoy your vision while you have it for our small work. PT-2
