What are stair-eyes?

Answer 1

Stair-eyes are a type of optical illusion created by placing a pattern on a surface, often stairs, that gives the appearance of depth or movement. They typically consist of contrasting colors or shapes that trick the brain into perceiving a three-dimensional effect.

The term can also refer to safety features added to staircases to enhance visibility and prevent accidents.
