I bought my Optivisor probably coming up on 20 years ago now
It's in use multiple times a week and I have no complaints (other than it magnifies both the figure and the brush, while I only really want it to magnify the figure
) I use it while wearing prescription glasses without any problems.
There are different magnifications and focal lengths, so check what you need first. Mine is a number 5, which apparently is 2.5x magnification with a focal length of 8".
It doesn't have any lights or anything, just the basic model.
