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. Do you still see the same person, or do you now see somebody different? 3. If you have good vision, keep looking at the photo but gradually move further back from your screen. Do you see anyone different in the picture now? Try it yourself and let us know how you get on in the comments section! There is a video at the bottom which explains the science behind the experiment. |
