Retinal cells are photo-receptor cells, meaning they are the cells that react to reflections of light. The two main types are rods (which are specially structured to sense differences in light and react to low levels of light) and cones (which are structured to react to different colors and work best in high levels of lights). So basically, you wouldn't perceive anything (you'd be blind) without these light detecting cells.
They help you see, because all the tissues in your eyes need to be composed of cells. Yeah, I need to write this down on my text work . . .
see and look
The eyes are important because they allow sight to occur. Sight is a very important sense that is used almost constantly.
Retina of human eye has 2 types of cells called cone cells and rod cells. Cone cells are photoreceptor cells in the retina. The function of these cells is in bright light. Rod cells function in less bright light. There are 4.5 million cone cells and 90 million rod cells in human retina. There are three types of cone cells. First type of cone cells called L which respond to light of long wavelength with peak sensitivity in the yellow region. Second type of cone cells are called M which respond to light of medium wavelength with peak sensitivity in the green region. Third type of cone cells called S which respond to light of short wavelength with peak sensitivity in the violet region.So, cone cells are not related with eye vision but are related with the perception of color. That is why if a person born without corn cell will be able to see but he will have another problem called color blindness.You can find the detailed diagram on this site examville.com for better understanding of the topic.
The cells are alive and metabolically active.
monitor its environment.
The rods cells are photoreceptor cells that require less light to function, therefore they are responsible for night vision.
No, sperm cells do not have eyes. They are microscopic cells that are specialized for fertilization and do not possess complex sensory organs like eyes.

eyes are extremely important to a wallaby. as you might know the eyes are needed to see!
the eyes main functions is to see and so that you want be blind
the function of goggles is to protect the eyes from harmful substances.
there is sulfur hydroxide in the oinons cells, so when you break those cells it lets out a type of fume that reacts with the salt water in your eyes. which makes your eyes water.
