Around 2% of males have red-green dichromacy, which is a genetic disorder of color vision whereone type of cone photoreceptor is missing. Here we investigate the color preferences of dichromats. We aim (i) to establish whether the systematic andreliable color preferences of normal trichromatic...
like a color is related to how easy it is to name. Up to half of the variance in trichromat males was related to quick response times in the naming test. "Because color perception has adaptive uses related to the speed and ease of processing (e.g., when locating something useful or d...

Although there's no way to truly know what non-human animals actually perceive, scientists can examine the cones inside the eyes and estimate what colors an animal sees. One of the techniques used to determine the color vision of fish is “microspectrophotometry.” This process analyzes the vis...
So what does someone who's colorblind see? Nothing that varied and exciting. With this brightly colored image, we'll look at how deuteranopia and protanopia (both types of red-green colorblindness) as well as tritanopia affect how someone sees. Image courtesy Henrik Sorenson/Stone/Getty ...

What causes color blindness? How is Graves' eye disease diagnosed? What is eosinophilic vasculitis? Why does abetalipoproteinemia cause retinitis pigmentosa? What are the symptoms of presbyopia? What are the signs of cataracts? How does toxoplasmosis cause hydrocephalus?
overflow:hidden when applied to an SVG element does end up diverging from the behaviour on other elements because replaced contents are clipped at the content edge and the scrollable values are ignored (i.e overflow:scroll is equivalent to overflow:hidden). ...

Both of these diseases attack the retina, rendering the rods and cones inoperative, causing either loss of peripheral vision or total blindness. However, it's been found that neither of these retinal diseases affect the ganglion cells or the optic nerve. This means that if scientists can ...
