Two identical pictures of a nurse are shown in the image given above. Readers have ten seconds to identify the three distinctions that exist between the two images.
The readers must have exceptional focus in order to distinguish the variations between the two images because they can be either extremely faint or quite noticeable.
According to studies, these kinds of activities activate the parts of the brain linked to memory and focus.
Kudos to the readers who managed to identify every distinction. Your eyes are the most perceptive.
