2 unusual facts about human eye


Aldose reductase inhibitor

Aldose reductase inhibitors are a class of drugs being studied as a way to prevent eye and nerve damage in people with diabetes.

Cutaneous and Ocular Toxicology

Cutaneous and Ocular Toxicology is an international, peer-reviewed medical journal that covers all types of harm to skin and eyes.


Alachlor

The EPA has described the following long-term effects when exposed to levels above the MCL in drinking water exposed to runoff from herbicide used on row crops: slight skin and eye irritation; at lifetime exposure to levels above the MCL: potential damage to liver, kidney, spleen; lining of nose and eyelids; cancer.

ENTPD2

It has been shown, by scientists from the University of Warwick, that E-NTPDase2 stimulates the growth of the eye: by testing the enzyme on tadpoles, the tadpoles were found to develop extra eyes on their body.

Eye injury

Physical or chemical injuries of the eye can be a serious threat to vision if not treated appropriately and in a timely fashion.

Four-dimensional space

The retina of the eye is also a two-dimensional array of receptors but the brain is able to perceive the nature of three-dimensional objects by inference from indirect information (such as shading, foreshortening, binocular vision, etc.).

Frederick Rushbrooke

He bought Burcot Grange, a country house in Burcot in 1927 but ten years later decided to donate it to the Birmingham & Midland Eye Hospital as an annex to treat inflammation of the eye.

Listing's law

Listing's law describes the three-dimensional orientation of the eye and its axes of rotation.

Mineral wool

Precautions need to be taken when handling a fiber product, as it can irritate the eyes, skin and respiratory tract.

Neuromyelitis optica

In 1894, Eugène Devic and his PhD student Fernand Gault described 16 patients who had lost vision in one or both eyes and within weeks developed severe spastic weakness of the limbs, loss of sensation and often bladder control.

Open fiber control

In telecommunication, Open fiber control is a protocol to ensure that both ends of a fiber optic cable are connected before laser signals are transmitted in order to protect people from eye damage.

Zonule of Zinn

The zonule of Zinn (Zinn's membrane, ciliary zonule) (after Johann Gottfried Zinn) is a ring of fibrous strands connecting the ciliary body with the crystalline lens of the eye.

Head-mounted display

This is the distance at which, given the average human eye rangefinder "baseline" (distance between the eyes or Inter-Pupillary Distance (IPD)) of between 2.5 and 3 inches (6 and 8 cm), the angle of an object at that distance becomes essentially the same from each eye.

Medical sign

The 1851 invention by Hermann von Helmholtz (1821–1894) of the ophthalmoscope, which allowed physicians to examine the inside of the human eye.

Simon von Stampfer

In 1832 Stampfer became aware through the Journal of Physics and Mathematics of experiments by the British physicist, Michael Faraday, on the optical illusion caused by rapidly rotating gears, in which the human eye could not follow the movement of the gear.

Wilhelm Karl Ritter von Haidinger

He was the first to observe the slight polarization dependence of the human eye, observed via the phenomenon now known as Haidinger's brush.
