I have worn glasses for short sight since I was twenty, so I had no problem focusing on figures. In the last five years, impending old age has also seen my close up vision deteriorate too.
A large pair of reading glasses has sorted that, although I did get some funny looks in the opticians holding up figures in front of various strengths of glasses. My prescription glasses are tuned for work, not painting, and I'm not paying hundreds of pounds for prescription painting glasses.
