It is caused by the distortion from the camera’s lens. The lens used in a camera is not a perfect piece of glass, so some form of distortion might be present in the image it captures. There is what we call radial distortion in which the light bends at a certain angle that deviates from a rectilinear plane.
What causes distorted images?
While optical distortion is caused by the optical design of lenses (and is therefore often called “lens distortion”), perspective distortion is caused by the position of the camera relative to the subject or by the position of the subject within the image frame.
What does it mean when an image is distorted?
A distortion is a change, twist, or exaggeration that makes something appear different from the way it really is. You can distort an image, a thought, or even an idea.
What causes optical distortion?
Optical distortion can be attributed to the lens profile and the lens design. Sometimes optical distortion results from certain lens elements that are used to reduce other visual deformations such as spherical aberrations.

What is coma in lenses?
Coma is an aberration resulting from a variance in magnification depending on the ray height at the lens. There are two types of coma: positive and negative. Negative coma occurs when rays hitting the lens further from the paraxial region focus closer to the axis than rays closer to the paraxial region.
Do camera lenses distort your face?
