Ott light makes something with a built-in magnifying glass. I got one because I do a lot of needlework. I love the light that it puts out--very, very clear and bright--but the lamp itself is terrible. The screws stripped out and I have had to rig up weird ways to keep the light from flopping down. It used to be that I could rotate it and adjust it in all kinds of directions but that quickly went away as the cheap plastic parts wore out. Mine is a floor lamp and was fairly expensive. I got the desk version for my dad, who also has macular degeneration, and that one has held up fine.
I've seen other lights with a built in magnifier but I don't know how well they work. The one on my Ott light was terrible, but I've seen pictures of some with a rectangular/square glass that look like they'd be better. I would avoid the round kind I have as it is very irregular in how it magnifies things.
The same type of light can be found in cheaper fixtures. I just saw some at my Costco (table version) but they didn't have a magnifier.
