A type of image that creates a three-dimensional effect when viewed with both eyes, often requiring the viewer to focus in a specific way.
When I looked at the stereogram, I could see the hidden 3D image appear before my eyes.
Stereogram → It is formed from "stereo-" (from Greek "stereos", meaning solid or three-dimensional) and "gram" (from Greek "gramma", meaning something written or drawn). A stereogram is an image that creates a three-dimensional effect when viewed in a certain way.
Think of 'solid' ('stereo-') and 'something written' ('gram') to remember that a stereogram is an image that gives a three-dimensional appearance.
