Short Sighted? Here’s How To See Something Clearly, Without Your Glasses

0

As anyone who’s hampered by their less-than-perfect eyesight will know, leaving behind your glasses or forgetting to put on your contact lenses makes for a very inconvenient day. Don’t worry too much though if you are short sighted, because the solution to this problem rests in your hands – literally.

As eloquently explained with typical visual resplendence by MinutePhysics, blurry images form when light entering your eye is too spread out on your retina. If you form a ring shape with your fingers and hold it over your eye, it will only allow certain beams of light onto your retina, mimicking the “focusing” effect of a pinhole camera.

You may look a little strange doing this all day though, so next time it might be best to just remember your spectacles.
