@ikar01: Having a similar but obviously less-severe problem with my own eyes, I empathize with you. Good luck with that appointment.

You can always get some 3X and 6X magnifying glasses for working on things like that. Amazon sells them for about 10 dollars for 3 pair. Hopefully your eye doctor has a better solution, but its something you can fall back on when you need to.
Magnification isn't an answer if the problem one of unclear vision rather than sharp vision.
My glasses correct my vision almost to 20/20 -- that's sufficient acuity to allow me to clearly see even the smallest parts of airplane kits. But I have dry eye -- lack of normal production of tears -- as a result of rheumatoid arthritis and various medications I have to take. My eyes often sting and feel scratchy, and I often have to wipe the corner of each eye with a tissue to remove bits of thick mucous which accumulate there. If I don't do that, and neglect to use artificial tears, and spend too much time at my computer or iPad, I have trouble reading, much less seeing frame lines on model canopies. The effect is like trying to look through a window that appears clean but actually has a thick film of grease and soot on it.
Magnification certainly helps, doesn't solve the problem: model parts, tools and supplies look bigger, but not clearer. I can "see" how severe "dry eye" could make model building difficult or impossible.
