Man, if only I had discovered the OAED sunglasses before I went and got laser eye surgery, I could have saved a bundle. Nah, I'm happy with the surgery but I must admit this is quite a breakthrough innovation.
Designed by Aleksander Mukomelov, the OAED sunglasses help to fix shortsightedness, longsightedness and cross-eye by strengthening the muscles in the eye with a technique called 'sight swinging.' This is achieved by placing dioptres of different strength all over the lenses so that the eye is constantly shifting focus. Simply an amazing idea.
