FocusPro Glasses Reviews Consumer Reports The technology utilized in FocusPro Glasses is based on the 'Alvarez Lens' system, which employs two wave-shaped polycarbonate plates for each lens. When the user rotates the adjustment dials on the side of the FocusPro Glasses, these two plates slide horizontally across one another. Once the left eye is calibrated, you repeat the process by covering the left eye and adjusting the right dial of the FocusPro Glasses until your vision is balanced and sharp in both eyes. This real-time customization means that if you switch from reading a paperback book to looking at a computer monitor three feet away, you can simply give the dials on your FocusPro Glasses a quick turn to re-focus for the new distance.
