Adlens® Emergensee Variable Focus Eyeglasses - You Set the Magnification for a Perfect View
An incredible new technology at a great price. These glasses allow you to adjust each lens so that you can have great vision for whatever you are doing. If you have different magnification needs for each eye, need to change reading glasses because of lighting conditions or you are tired of buying readers as your magnification needs change, Emergensees are for you. Here's how they work. All you have to do is turn a little knob on the frame above each lens. Each variable focus lens allows the user to manually adjust to his or her needs for clarity. They are easily adjusted for a wide range of spherical powers from -6.0 to +3.0D. Incredible!
