Yes, according to my optometrist

Two possible answers: 1. If the curve is really exaggerated and really rounds boxes so they tend to look like a ball that "kind of" have four corners, then you may have a "fisheye" lens. 2. Some less-expensive non-fisheye lenses have what is called "barrel" distortion or "pincushion" distortion. Barrel distortion slightly curves box edges out until they look a little over-inflated. Pincussion distortion slightly curves box edges in until they look like someone is sucking the contents out of the box. Many of the less expensive zoom lenses have barrel distortion at one end of their zoom range and pincushion distortion at the other end of their zoom range.

Aperture distortion, also known as lens distortion or optical distortion, refers to the various aberrations or imperfections that can occur in photographs due to the characteristics of the camera lens and its aperture (the opening through which light enters the camera). These distortions can manifest in different ways:

Barrel Distortion: This type of distortion causes straight lines to appear curved outward, resembling the shape of a barrel. It typically occurs with wide-angle lenses and can make objects at the edges of the frame appear stretched or bulging.

Pincushion Distortion: Pincushion distortion is the opposite of barrel distortion. It causes straight lines to curve inward, like the shape of a pincushion. This distortion is more common in telephoto lenses.

Chromatic Aberration: This type of distortion occurs when different wavelengths of light do not converge at the same point, resulting in color fringing, especially at high-contrast edges in an image.

Vignetting: Vignetting causes the corners or edges of an image to be darker than the center. It happens when the aperture is not evenly transmitting light across the entire frame.

Spherical Aberration: Spherical aberration can cause blurriness or softness in an image, particularly around the edges, due to the way light rays are bent by the lens elements.

Distortion from Aperture Shape: The shape of the aperture itself (e.g., circular, hexagonal) can impact the appearance of out-of-focus highlights or "bokeh" in the background of a photograph.

Photographers often aim to correct or minimize these distortions through lens design, post-processing techniques, or by choosing lenses suited to their specific needs.

Copenhagen Distortion was created in 1998.

Social Distortion was created in 1978.
