Just what I needed. Works perfectly. Now I don't have to switch between glasses .

Nice glasses for folks who feel....
Nice glasses for folks who feel cheated when they go to the fancy eye places. These work well. with good optical quality. My only suggestion would be for a little less yellow intensity on the tint option.

works for me
Works for me. Perfect for working at my computer. I got the 1.50/2.50. I just wish there was an extra wide option.

Work great
I don't need two different strengh glasses, one pair for reading computer screen and reading close up for books etc. Really like them.

Great but did not work for me. Your milage may vary. Worth a look.
These are just want I needed post-cataract surgery. The folks here were helpful and shipping was fast. Sadly, the placement of the bifocal insert was just too low for my needs and I found myself looking through the top line much of the time. This will vary by individual so it may work fine for you. It is worth trying out! And the refund was swift and easy! Cheers
