Polarizing sheets are used in liquid-crystal displays, optical microscopes and sunglasses.Since Polaroid sheet is dichroic, it will absorb impinging light of one plane of polarization, so sunglasses will reduce the partially polarized light reflected from level surfaces such as windows and sheets of water, for example.
The condition primarily involves the retina, the light-sensitive tissue at the back of the eye, and occasionally the optic nerve, which carries visual information to the brain. When suffering from Cyanopsia some individuals may also experience blurred vision , or heightened sensitivity to bright light, which can make well-lit environments ...
A Hollenhorst plaque (also known as a retinal cholesterol embolus) is a cholesterol embolus that is seen in a blood vessel of the retina.It is usually found when a physician performs ophthalmoscopy, during which a plaque will appear as a small, bright crystal that is refractile (reflects the light from the ophthalmoscope) and yellow.

Herapathite, or iodoquinine sulfate, is a chemical compound whose crystals are dichroic and thus can be used for polarizing light. It was discovered in 1852 [1] by William Bird Herapath, a Bristol surgeon and chemist. One of his pupils found that adding iodine to the urine of a dog that had been fed quinine produced unusual green
Polaroid Eyewear manufactures polarized sunglasses and polarized lenses, as well as optical frames, reading glasses, and clip-on lenses. Polaroid Eyewear was a part of the StyleMark group and sold to the Safilo Group in November 2011.
The rotation of the crystal planes can be right or left-handed, again producing opposite optical activities. On the other hand, amorphous forms of silica such as fused quartz, like a racemic mixture of chiral molecules, has no net optical activity since one or the other crystal structure does not dominate the substance's internal molecular ...
In 1991, police discovered Jeffrey Dahmer had 84 polaroid photos depicting 17 murders he committed between 1978 to 1991. The act is shown in 'Monster: The Jeffrey Dahmer Story' on Netflix.
The Amsler grid showing the visual perception of the left eye of a person experiencing metamorphopsia (straight lines appear bent or curved) [1] [2]. Metamorphopsia (from Ancient Greek: μεταμορφοψία, metamorphopsia, 'seeing mutated shapes') is a type of distorted vision in which a grid of straight lines appears wavy or partially blank.
