Cells in the the retina called cones (for colour perception and in greatest numbers in the macula) and rods (for black and white).
Cones (for color vision in bright light) and rods (vision in dim light)
The RETINA in covered with photorecptors. The MACULA has the highest concentration of these and the centre of that is the FOVEA, where vision is sharpest.

retina
The macula. It is the central area of the retina, where the lens forms the central part of an image. It contains a high density of cone type light sensitive receptors.
The photoreceptors commonly referred to as "Rods", which are found in the retina, are responsible for night vision. (scotopic vision) "Cones" are responsible for colored vision with brighter light conditions. (photopic vision)
The pupil is the part of the eye through which light passes.
The eye uses both the pupil and iris to control how much light enters the visual receptors. here is a source to read more: http://www.biologymad.com/NervousSystem/eyenotes.htm
The center of an eye ball contains a transparent substance known as aqueous humor. The back of the eyeball, closest to the brain, is where the light-sensitive retina is located.
The retina is the part of the eye that contains light receptors.
The retina is the part of the eye that contains light receptors.
Light receptors called rods and cones are found in the retina of the eye. Rods are resposible for discerning light as blackand white and the cones colour.
It's your eye. That's what my gut tells me, definitely the eye
Retina in the eye contains sensory cells. Retina has got rods and cones. Cones are responsible for colour vision. Rods are responsible for vision in less amount of light.
The eye's visual receptors reside within the retina. The eye's visual receptors consist of four different types of receptors including rods, blue cones, red cones and green cones.
You have rod cells and cone cells as receptors in your eye. Rods are for intensity of the light. Cone cells are for color vision.
The macula. It is the central area of the retina, where the lens forms the central part of an image. It contains a high density of cone type light sensitive receptors.
Light receptors are found in the eye. There are two types of receptors; rods and cones. Rods produce the black and white pigments and the Cones produce the color pigments.
I believe you mean the "retina". It appears black when you look into your friend's eyes, but it really is red. It appears black because of the refraction of light. The eye is designed to take light in, not let it out. The retina is the lining in the back of the eye that contains the light receptors, and many blood vessels as well.

Rods are light-sensitive receptors in the retina of vertebrates.
