When you look at this photo, do you see Marilyn Monroe or Albert Einstein? This strange illusion makes for an interesting eye test and it has nothing to do with color or lighting. There’s really no trickery involved.
When you first look at the photo, you should see a blurry version of Albert Einstein. If you step back and view the photo from a distance, you’re more likely to see Marilyn Monroe. That means you probably have good vision. The further away you can still see Einstein, the better your eyes likely are.
If you wear glasses, take them off and try the test again. If you’re like me, you'll get different results. You can also alter the results by squinting your eyes.
The image is a hybrid. It combines a low spatial frequency image with a high spatial frequency image. How close you are to the picture affects how well your eyes can focus and pick out certain details. If your eyes are normal, you should be able to pick out finer details up close, and see Einstein. As you get further away, it’s harder to see find details and you'll probably only see the general features of Monroe.
It’s a fun eye test that may actually catch a problem with your eyesight. But don’t take the test’s word for it. Have your eyes tested by a qualified optometrist or ophthalmologist.
According to the Mayo Clinic, an eye exam can detect eye problems at their earliest stage — when they’re most treatable. That’s why eye exams are so important. Have your eyes checked at the first sign of a problem. If you don’t have vision problems and are healthy, this is when to have your eyes examined:
- Children: the first comprehensive eye exam should be done between the ages of three and five.
- School-age children and teens: vision test before first grade, then every two years.
- Healthy adults without vision problems: vision test every two to four years. After age 65, every one to two years.
You'll need to have your eyes examined more frequently if you have vision problems or certain health conditions.
