Some exhibit realistic eye-like markings, whilst others have adapted the eyespots to form crescent moon or angular shapes or have lost their wing scales to create transparent windows. They are medium to very large moths, with adult wingspans ranging from 7.5 to 15 cm, in some cases even more.
An ocular prosthesis, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation, evisceration, or orbital exenteration. Someone with an ocular prosthesis is altogether blind on the affected side and has monocular (one sided) vision .
[2] [3] The physical origins of eye lens transparency and its relationship to cataract are an active area of research. [4] Since it has been shown that lens injury may promote nerve regeneration, [5] crystallin has been an area of neural research. So far, it has been demonstrated that crystallin β b2 (crybb2) may be a neurite-promoting factor. [6]
The vitreous humor is a transparent, colorless, gelatinous mass that fills the space in the eye between the lens and the retina.It is surrounded by a layer of collagen called the vitreous membrane (or hyaloid membrane or vitreous cortex) separating it from the rest of the eye.
Ceiling of the Treasure Room of the Archaeological Museum of Ferrara, Italy, painted in 1503–1506. Trompe-l'œil (French for 'deceive the eye'; / t r ɒ m p ˈ l ɔɪ / tromp-LOY; French: [tʁɔ̃p lœj] ⓘ) is an artistic term for the highly realistic optical illusion of three-dimensional space and objects on a two-dimensional surface.
A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those with partial or total blindness. Many devices have been developed, usually modeled on the cochlear implant or bionic ear devices, a type of neural prosthesis in use since the mid-1980s.
Use whatever you have, like your surfboard, diving equipment, or even your fists, to hit the shark in sensitive areas (eyes and gills). However, don’t start a fight with a shark. Fighting back ...
The Pacific barreleye fish [1] (Macropinna) is a genus of ray-finned fish belonging to Opisthoproctidae, the barreleye family.It contains one species, M. microstoma.It is recognized for a highly unusual transparent, fluid-filled shield on its head, through which the lenses of its eyes can be seen.
