I went to Target to pick up some medication and noticed a box sitting on the counter at the pharmacy. Inspecting the box I found it was filled with these cards, They were fresnel lens for old people who can't see. They looked very similar to the focusing screens I had been researching the night before.
See the similarities?
I think the only difference is the actual focusing screens are translucent (I think) and mine is transparent. Anyone think this will work.
