II. Photochromic Bifocal Lens







Single vision lenses are used to sharpen your focus for either nearby or faraway images. However, they cannot be used to sharpen your vision for both. Bifocal lenses enhance your vision for both nearby and faraway images.



























Bifocal lenses consists of two prescriptions. A small portion in the lower part of the lens contains the power to correct your near vision. The rest of the lens usually is for your distance vision.
























The photochromic bifocal lenses go darken as sunglass when you go outdoors. They protect your eyes from bright light and UV rays, allowing you to read and view clearly at the same time. Lenses will become clear again indoors within only a couple of minutes. You can easily enjoying indoor activities without taking them off.
