Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
The concept of perspective distortion has fascinated artists, architects, and scientists for centuries, evolving alongside the development of visual culture and optical theory. Perspective distortion refers to the manipulation of visual perception through deliberate techniques that create altered or exaggerated views of objects or scenes.
Visual artifacts (also artefacts) ... A crush artifact is an artificial elongation and distortion seen in histopathology and cytopathology studies, presumably because ...
A pathological visual illusion is a distortion of a real external stimulus [32] and is often diffuse and persistent. Pathological visual illusions usually occur throughout the visual field, suggesting global excitability or sensitivity alterations. [33]
In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
An illusion is a distortion of the senses, which can reveal how the mind normally organizes and interprets sensory stimulation.Although illusions distort the human perception of reality, they are generally shared by most people.
Anxiety and headaches accompany the episodes of visual distortion associated with epilepsy. While Valproic acid has been used to treat this type of seizure, [20] anti-seizure medications appropriate for focal-onset seizures, like oxcarbazapine, have also been used successfully in the treatment of epilepsy-related macropsia.

The Amsler grid showing the visual perception of the left eye of a person experiencing metamorphopsia (straight lines appear bent or curved) [1] [2]. Metamorphopsia (from Ancient Greek: μεταμορφοψία, metamorphopsia, 'seeing mutated shapes') is a type of distorted vision in which a grid of straight lines appears wavy or partially blank.
