Einstein or Monroe?

Who do you see?

              

 

With this picture we can proove how good is your eyesight and could help you figure out if you need glasses or contacts.

• If you are in a normal distance from the screen and have a good eyesight, you should be seeing Albert Einstein.
•     However, if you see Marilyn Monroe, you should consider wearing glasses or contacts.
•       If you are wearing glasses right now, take them off and the image might change.                                          
 
If  changed  the distance and size of the picture, all of us can see the effect.

 If the image is farther, it is more likely to see Marilyn Monroe, because our eyes only pick up the broadest strokes of an image from the distance, but when you come closer to the image, you will start noticing the finer details of Einstein.

Try walking away from the computer and you might see the image change. It changes at a different distance to different people, because our eyes are different. The farther away you can stand and still see Einstein, the better your eyesight is.

 

How and why does this happen?

This is an example of a HYBRID IMAGE, a low spatial frequency of a picture (Monroe) is combined with a high spatial frequency of a picture (Einstein).

Depending on how you focus or pick up contrast your eye will only pickup certain details. If we are close to the image we can pick up fine details like Eintein´s wrinkles and mustache, but if the distance is increased or your vision is poor the image becomes blurry, and your ability to pick up details goes away. So you only see the shape of the mouth,nose, and hair, making it look like Monroe.   

 

Why did this article interest me?

This article interested me, because the fact that only a simple image can determine whether your eyesight is good or bad is amazing. Also, it is very interesting how we can see different things and how the image can change at a certain distance. I think that this is a very interesting topic.
