Gerald! That photo of you with all your magnifiers is priceless! A 'third hand' won't help you there!
I agree.....with age: Light, light and more light! I use one of the grey optivisors with a swing out eye loup attached. Fresh into a modeling session, I am fine without eyeglasses.......if it's a marathon session........I need the glasses beneath the visor.
I've worn glasses since I was 36. Visiting my Mom one day she saw me reading the baseball box scores in the paper. I was holding the page at ARM'S LENGTH in order to read the print! I didn't even realize it! That was 18 years ago!
