You want to check out how good is your vision? The team who is behind of this popular YouTube channel “AsapScience” through this video will give you the answer to this question. The test is really simple. In the video the AsapScience explains that if you have a good vision and you are at a decent distance from the screen, then you should see a photograph of Albert Einstein, but if you see Marilyn Monroe then it is probably time for eyeglasses.
When the image is located at a considerable distance is normal to see Marilyn, because the ability to spot details decreases, but as it gets closer then you should start to see Einstein.
If you want to check out pause the video and zoom the screen – from how far you can see Einstein, the better your appearance.
