Here is a single image that can tell you how good your eyesight is. Or so scientists say anyway! You can try this fascinating test for yourself. Here are the instructions: 1. Look at the image while sitting a normal distance from your screen. Who is the person in the photo? 2. If you wear glasses, take them off and then look at the image again from the same distance.
