These magnifiers are a bit bigger than the ones at the bottom of Lake Agnes, but I think they'll work just fine. I like to clip them to my hat when not in use to decrease weight on my sunglasses. Service at BQA was excellent.
For 2008, we've redesigned our Flip 'n' Focus. Increasing the lens size of our magnifiers offers a larger field of magnified view. Now you'll see even better than before. You won't know that you've got the Flip 'n' Focus clipped to your regular glasses until you need them. Just flip the lenses down for increased magnification and up for safe storage. Protective case included. Note: Sunglasses not included.
