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 retina contains small, specialized neurons called bipolar cells that transmit information from light -
sensitive photoreceptor cells to ganglion neurons, which send information to the brain for interpretation as images.
Light enters through the pupil and passes through four layers in the retina before reaching the light -
sensitive photoreceptors.
Soon after, the light -
sensitive photoreceptors begin to perish.
These wavelength -
sensitive photoreceptors were identified soon after and are known as melanopsin - containing ganglion cells.
Bypassing damaged retinal cells The light -
sensitive photoreceptors made by the rod and cone cells in the retina also belong to the GPCR class.
In the future, ultrafast laser crystallography promises to illuminate a broad range of biomolecules, from light
sensitive photoreceptors to other vital proteins.
We have compared the response times of green -, blue -, and UV -
sensitive photoreceptors in the bumblebee Bombus terrestris.
These wavelength -
sensitive photoreceptors are known as melanopsin - containing ganglion cells.

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.
Instead of catching light on film, digital cameras use an array of light -
sensitive photodiodes that function much like the
photoreceptors in an eye.
Like many animals, humans have three kinds of
photoreceptors in their eyes, each
sensitive to a different colour.
The
photoreceptors in the retina, at the back of the eyes, are the primary light

sensitive to light toward the bluish end of the visible spectrum.
With age, our eyes accumulate waste in retinal pigment epithelium (RPE), which supports the life and function of
photoreceptors (light
sensitive cells in the eye); in advanced stages, RPE and
photoreceptors die.
