I have a magnifying lamp like most do.
I put a natural spectrum lamp in it like most pet stores sell for reptilian enclosures. It's supposed to emulate the sun's light and make the colors of plants and reptiles natural. Here's an example.
I think they cost around $6.95 or so for the lamp. My magnifier I spent all of $19.95 on.
But my Mag Eyes are the best thing I've gotten for my tiring eyes. They work very natural with your eyes, head and neck. (Especially when you put them on right side up!)
My vision correction so far is simply 1.75 ready readers. But I wear them so that I look over the top for normal vision.
So I have a sort of make shift tri-focal when tying.
