Not exact matches

That light goes through the transparent liquid behind the lens and strikes the retina, a thin film of light - sensitive nerve cells that line the back of the eye.

In most vertebrates and some mollusks, the eye works by allowing light to enter it and project onto a light - sensitive panel of cells known as the retina at the rear of the eye, where the light is detected and converted into electrical signals.

Neurons that fire in response to horizontal and vertical movements had already been found in the retinas of mammals, but the only cells known to be sensitive to approaching objects were in the brain.

LCA is a rare inherited eye disease that destroys vision by killing photoreceptors — light - sensitive cells in the retina at the back of the eye.

Each of our retinas has a small patch of densely packed, light - sensitive cells called the fovea.

The photoreceptors in the retina, at the back of the eyes, are the primary light sensitive cells that allow us to see: they convert light into electrical signals.

Most causes of untreatable blindness occur due to loss of the millions of light sensitive photoreceptor cells that line the retina, similar to the pixels in a digital camera.

The condition is hereditary or age - related, and causes degeneration of the photoreceptors — light - sensitive cells in the retina — leading to blindness.

«If you take a lens that has that much power and point it directly at the sun, the energy becomes very high,» and is enough to literally burn holes in the retina, or the light - sensitive cells at the back of the eye, Van Gelder said.

The number of damaged and dying cells in the retina — a light - sensitive layer of nervous tissue in the eye — did not change in the castrated males.

Each photopigment is sensitive to light of a particular wavelength, and the primate visual system detects colors by comparing the relative activity of cells in the retina that bear each of the three photopigments.

Age - related macular degeneration, a disease that slowly degrades light - sensitive cells in the retina, is the leading cause of vision loss and blindness among people 65 and older, according to the Centers for Disease Control...

The term describes the creation of a coordinated connection that allows positional information from a grid of sensors, in this case the light - sensitive cells in the retina, to be smoothly and systematically transferred to their target, the structures in the brain that interpret information from the eyes.

This research points to exciting new possibilities for preventing or reversing the disabling vision loss caused by age - related macular degeneration, diabetic retinopathy, retinitis pigmentosa, glaucoma, and other diseases that damage the retina, the layer of light - sensitive nerve cells that line the back of the eye.

Stargardt's generally refers to a group of inherited diseases causing light - sensitive cells in the inner back of the eye (retina) to deteriorate, particularly in the area of the macula where fine focusing occurs.

Third place went to Charlie Granger, a PhD candidate in optics, who used adaptive optics technology to show the natural fluorescence of retinal pigment epithelial cells, which form a layer only one cell deep, on the backside of the eye's light - sensitive retina.

This is because melanopsin — a photopigment found in specialized cells of the retina involved in the regulation of circadian rhythms — is most sensitive to blue light.

The lack of color sense is balanced by the dog having many more rods, light - sensitive cells on the retina, than people do.

The majority of deep - sea fishes in the dysophotic zone possess retinas with rod cells sensitive to short - length blue light, between 480nm - 490nm (Kenaley, DeVaney, & Fjeran, 2014).
