Answer:
Mirage
An optical illusion caused by atmospheric conditions, especially the appearance of a sheet of water in a desert or on a hot road caused by the refraction of light from the sky by heated air.
"the surface of the road ahead rippled in the heat mirages" can be an example
Spherical aberration in lenses
The shape of a spherical lens causes a problem called spherical aberration.
In spherical aberration, parallel light rays that pass through the central region of the lens focus farther away than light rays that pass through the edges of the lens. The result is many focal points, which produce a blurry image. To get a clear image, all rays need to focus at the same point.
