I have trifocals. Bottom lens stops about 16" out. Mid lens goes from there to about 3'. Main lens goes to infinity. Everything is crystal clear.I don't have cataracts (yet), but I'm so far resisting the notion of bifocals. In brighter light I don't have trouble reading, but in dim light I don't get to take advantage of the pinhole camera effect of contracted pupils (obviously not entirely a pinhole but focusing is considerably easier with contracted iris than expanded) and so can't read so well.
My mom was an artist. She had custom upside down trifocals for painting, with the closeup lens on top, mid lens, then main lens on bottom. Think about standing in front of an easel and having to tip your head back everytime you wanted to see the canvas. Your neck would get pretty sore. Upside down allows your neck to stay at neutral position when facing your painting. It makes sense.
