Full redraw: Group labels in accordance with the "Foundational Model Explorer." Added "Macula" and "Uvea" and removed "Zonular fibres." It has given better visibility inside the eye. The eyeball shape and size of different parts of the eye are now real...
The vestibulo-ocular reflex is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement in response to neural input from the vestibular system of the inner ear, thus maintaining the image in the centre of the visual field. For example, when the head ...
The Eye of Providence can be found on the reverse of the Great Seal of the United States, as seen on the U.S. $1 bill, depicted here.. The Eye of Providence or All-Seeing Eye is a symbol depicting an eye, often enclosed in a triangle and surrounded by rays of light or a halo, intended to represent Providence, as the eye watches over the workers of mankind.
The eyes of most cephalopods, fish, amphibians and snakes have fixed lens shapes, and focusing is achieved by telescoping the lens in a similar manner to that of a camera. [5] The compound eyes of the arthropods are composed of many simple facets which, depending on anatomical detail, may give either a single pixelated image or multiple images ...
The movement of the eye is controlled by six distinct extraocular muscles, a superior, an inferior, a medial and a lateral rectus, as well as a superior and an inferior oblique. The superior ophthalmic vein is a sigmoidal vessel along the superior margin of the orbital canal that drains deoxygenated blood from surrounding musculature.

In his essay Nature , the metaphor stands for a view of life that is absorbent rather than reflective, and therefore takes in all that nature has to offer without bias or contradiction.
The accessory visual structures (or adnexa of eye, ocular adnexa, etc.) are the protecting and supporting structures of the eye, including the eyebrow, eyelids, and lacrimal apparatus. The eyebrows, eyelids, eyelashes , lacrimal gland and drainage apparatus all play a crucial role with regards to globe protection, lubrication, and minimizing ...
Floaters or muscae volitantes are slowly drifting blobs of varying size, shape, and transparency, which are particularly noticeable when viewing a bright, featureless background (such as the sky) or a point source of diffuse light very close to the eye. They are shadow images of objects floating in liquid between the retina and the gel inside ...
