This worked the way I wanted it to. It is very powerful and with the light it adds more clarity to what you are doing.
Great tool for sizing ladies watches
I bought the glasses to make it easier to seeing the pins on my wife's watches. I have been sizing both or our watches for a least 5 years, and sizing a ladies watch can be very challenging. The glasses do a great job of magnifying the pins, and the lights really make the job a cinch.
The lenses may cause the glasses to slide down on your nose, but bending the ear loops will solve this issue. I really should have purchased a pair of these years ago.
