I have been pleased with my new sunglasses. They fit over my existing glasses and you hardly know that you have them on
The glasses arrived well packaged and in a reasonable period of time. They just fit over my prescription glasses which I measured carefully before ordering. They cut out most of the light coming in from above and fit closely without slipping. I also like the look of them,
The dimension of my existing glasses were borderline as far as fit but feel they will work. I like how I can wear a helmet and put glasses on and off while wearing the helmet.
I would recommend them to friends.
I like the glasses but they don't come close to fitting over my regular glasses and I went by your measurment chart.
I was just looking for this some cheap clip on sunglasses, and I found these. These sunglasses are way better. They fit perfectly over my glasses. I really like that the stems also have shades instead of solid plastic that just blocks your field of vision.
