This Bonus Buy was only available in 3.0 We hope to have other powers available soon. The clear bifocal comes with a magnetic clip to make it a polarized sun bifocal. The clip is very secure and hard to detect. It looks like a very upscale sun bifocal. The frame has a spring hinge for a flexible and comfortable fit. The lenses are 100% UV protected. If you can use a 3.0, you will love this! Frame Measurements: 5 3/8" x 1 5/8" (temple to temple x height of lens)
