003429. In medicine, the caloric reflex test (sometimes termed 'vestibular caloric stimulation ') is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal. This method was developed by Robert Bárány, who won a Nobel prize in 1914 for this discovery.
That’s because you can get a corneal ulcer, which is an infection on part of the eye that a contact covers. “It’s not going to happen every time, but when it happens, it’s terrible ...

Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen ( O. 2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Historically, the central nervous system condition was called the Paul Bert effect ...
Refraction. A ray of light being refracted in a plastic block. In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium. [ 1] Refraction of light is the most commonly observed phenomenon, but other waves such as sound ...
Atmospheric refraction. Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [ 1] This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased ...
Underwater vision. Scuba diver with bifocal lenses fitted to a mask. Underwater vision is the ability to see objects underwater, and this is significantly affected by several factors. Underwater, objects are less visible because of lower levels of natural illumination caused by rapid attenuation of light with distance passed through the water.
Atmospheric circulation. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant.
