Answer:
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.
Explanation:
The shape of a spherical lens causes a problem called spherical aberration. The simplest method of reducing spherical aberration is to place an aperture, hole or "stop", in front of or after the lens. The aperture blocks out rays that blur the image.
