It is small glasses if you have a thinner face or want them to be closer to your head than regular safety glasses. They're on sale all my crystal glasses I make.It's such a pretty faon to have to wear those safety goggles at work and still watch sheek and sexy. These are made with light pink crystals ab swarovski that I put in two rows on the side and only one row on the front part. The arms are pink and will pass all safety standards for ansi z87.1-2003. These are clear no strength and I also have it in regular size and I have bifocal readers in my etsy store that are also available. There is a pink ribbon on these arms and a donation goes to breast cancer research.
