You may have learned in school that there are two types of light-sensitive cell
in the human eye: rods, which provide black and white vision in low-light conditions, and cones, which work in bright light and enable us to see colour.
A few years ago, scientists discovered another type of light-sensitive cell
in the eye.
Fluid passes in a narrow film through a light source, which has a light-sensitive cell

Similar to a digital camera sensor, light-sensitive cells
in the eye (photoreceptors) detect wavelengths of light within specific ranges and at particular locations.
ISLAMABAD -- Recent research has uncovered how light-sensitive cells
in the eye can reset the internal clock when exposed to light.
The latter are light-sensitive cells
in the back of the eye that transmit information to the brain when activated, and unfortunately these cells are unable to regenerate on their own in mammals.
Photoreceptors are light-sensitive cells
in the retina in the back of the eye that signal the brain when activated.
Specialist cells in the eye known as Muller glia divide and turn into light-sensitive cells
. Dr Chen said: "This is a very powerful cell repair machinery.
ISLAMABAD -- The exposure to blue light from smartphones and laptops triggers 'poisonous molecules' that are generated in eye's light-sensitive cells
and can cause macular degeneration and other eye illnesses.
Secondly it protects and prevents the steady breakdown of light-sensitive cells
in the center of the retina - the macula and lastly, increases blood flow into the eye boosting your antioxidant defense.
