We were having basketball photos taken the other night and I watched one of the photographers get kids into the just right frame of mind to have their photo taken. She was amazing! Great attitude, knew just what to say to get it right. As she looks to the image on her digital camera she lifts two separate lenses of her glasses up to her eyes and they snap together so she can see the image clearly, as she looks back to her audience of one she separates them and they continue to just hang around her neck! Effortless and she always knows where they are. I was intrigued!
Here's a picture I found online. It seems they are sold as Click Reading Glasses . Very functional and all the rage! If you get some let me know how you like them!
