One image could let you know if your eyesight it up to par.
The optical illusion released by ASAP Science is the combination of a low spatial frequency of one photo (blurred details) and a high spatial frequency of another (with visible details).
Depending on how well you are able to focus or pick up contrast, you will see something different.
Up close, you can see fine details like Einstein's mustache and wrinkles but farther away (or with poor eyesight) you can only see general features, making it look like Marilyn Monroe.
