I'd noticed that the quality of my painting had been suffering, particularly when I didn't wear my specs, but even when wearing the glasses I have been using (an old prescription). Today I have taken delivery of a new pair of bifocals, with a focal length of around 12" that is perfect for painting, and a long distance prescription that will help me focus on my other favourite hobby, watching the box! They are glare free which should also help whilst painting under my lamp, and lightweight.
When I just looked at these minis, painted by Andres of Einar Olafson, I could see detail I've never noticed before! :-) On the downside, my painting rate will slow right down... :-(
