Trace of saccades of the human eye on a face while scanning Saccades during observation of a picture on a computer screen. In vision science, a saccade (/ s ə ˈ k ɑː d / sə-KAHD; French:; French for 'jerk') is a quick, simultaneous movement of both eyes between two or more phases of focal points in the same direction.

An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species.
Saccadic masking, also known as (visual) saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer.
Biomimetic architecture is a branch of the new science of biomimicry defined and popularized by Janine Benyus in her 1997 book (Biomimicry: Innovation Inspired by Nature). ). Biomimicry (bios - life and mimesis - imitate) refers to innovations inspired by nature as one which studies nature and then imitates or takes inspiration from its designs and processes to solve human problem
The four-eye butterflyfish conceals its eyes using a disruptive eye mask, a type of camouflage, and displays false eyespots that mimic its eyes near its tail.. At the first level, an animal acts because it cannot do otherwise, it is programmed to deceive in a certain way.
One of the early examples of biomimicry was the study of birds to enable human flight.Although never successful in creating a "flying machine", Leonardo da Vinci (1452–1519) was a keen observer of the anatomy and flight of birds, and made numerous notes and sketches on his observations as well as sketches of "flying machines".

The specific timing pattern of microsaccades in humans changes during reading based on the structure of the word being read. [ 10 ] [ 11 ] Experiments in neurophysiology from different laboratories showed that fixational eye movements, particularly microsaccades, strongly modulate the activity of neurons in the visual areas of the macaque brain.
Children are often allowed to learn without restrictions and with minimal guidance. They are encouraged to participate in the community even if they do not know how to do the work. They are self-motivated to learn and finish their chores. [37] These children act as a second set of eyes and ears for their parents, updating them about the ...
