Do You See Marilyn Monroe or Albert Einstein? This Reveals How Good Your Eyesight Is

Want to test your eyesight with this hybrid image?

    Is it Marilyn Monroe or Albert Einstein?

    If there is someone around, ask them who they see.

    Now, start taking steps back as you look at the image.

    Does the image change?

    Or, try squinting your eyes and look at the photo.

    You probably won’t be surprised to hear that the person most people see when they are close to the image is Albert Einstein, however, not everyone gets to maintain the same image as the distance changes. As they get farther away from the image, most people are shocked by the sudden transformation of Albert Einstein into Marilyn Monroe. The same happens if you change the size of the image, in which case the smaller one will be perceived as Marilyn Monroe, whereas the bigger image will show clear details of Albert Einstein’s face.

    If you find it hard to find the face of Albert Einstein, chances are you need to see your eye doctor, as your eyesight probably isn’t very good. If you already wear glasses, then you need a stronger ones.

    For the rest of you, who clearly see Albert Einstein at first, your eyesight is as good as you can keep the unchanged image.

    How hybrid images determine our eyesight

    The image above, created by Dr. Aude Olivia from MIT is a hybrid image which is made by taking two separate images and combining low spatial frequency components of one with high spatial frequency components of the other. In this way, as we are closer to the image, we can more easily spot the fine lines and details (in this particular case the wrinkles on Albert Einstein’s face), whereas if the image gets smaller, or if we look at it from bigger distance, our eyes are only able to see general details like shape of hair, mouth or nose, features that, in this case, belong to Marilyn Monroe.

    The author of the image explains the concept of hybrid image:

    “The phenomenon of hybrid images arises from the multi-scale processing of images in the human visual system. By taking into account perceptual grouping mechanisms, one can build compelling hybrid images with two different stable interpretations: one that appears when the image is viewed up-close, and the other that appears from afar.”

    The explanation of how hybrid images are able to determine the quality of our eyesight lies in the fact that our ability to focus and see clear, fine details from any distance defines good eyesight. Therefore, people who struggle with blurred image even at regular viewing distance, should consider seeing an eye doctor.

          8 Smart Home Gadgets You Need in Your House

          We’ve all done it. We’ve gone out and bought useless gadgets that we don’t really need, just because they seemed really cool at the time. Then, we are stuck with a bunch of junk, and end up tossing it or trying to sell it on Ebay.

          On the other hand, there are some pretty awesome tech inventions that are actually useful. For instance, many of the latest home gadgets do some of your work for you, from adjusting the home thermostat to locking your front door. And, if used as designed, these tools should really help to make your life a lot easier—and that’s not just a claim from some infomercial trying to sell you yet another useless gadget.

          Take a look at some of the most popular “smart gadgets” on the market:

          1. Smart Door Locks

          A smart lock lets you lock and unlock your doors by using your smartphone, a special key fob, or biometrics.

You can even use a special app to let people into your home if you are not there to greet them.

From meat thermometers to kitchen scales, you’ll find a variety of “smart” gadgets designed to make culinary geeks salivate.

          3. Mini Home Speaker Play:1

          If you love big sound, but hate how much space big speakers take up, and if you want a stereo system that is no bigger than your fist, check out the Play:1 mini speaker. All you have to do is plug it in, connect, and then you can stream without worrying about any interruptions or interface. You can even add onto it, and have different music playing in different rooms.
