Color blindness (or more correctly, Color deficiency, as almost nobody is totally colorblind) is an inherited abnormality caused by a lack of one or occassionally two of the necessary primary color pigments in the cones of the retina. This is quite common in males (8%) and comparatively rare in females (.04%). For a female to be color deficient, both her mother and father would have to be color deficient. The retina is the very thin, transparent membrane lining the back wall inside the eye. It gathers images of the "outside world" and transmits them as electrical impulses to the brain for interpretation by way of the optic nerve. The eyeball functions kind of like a camera with an internal lens (crystalline lens) and film (retina).
they are used in eye hospitals to see if the core of your eye is still functioning properly.
well dogs eye sight is good but not good because there is no colour
the cornea is the coloured part of the eye
It is called the iris
the eye is the weakest part of a storm

because some animals don't have a CONE in on their eye.
Yes, he is colorblind in his right eye
There is no way to tell what color the eye sees better for everyone. Some people are colorblind for example.
Dilated (spelling correction) is a word describing when a pupil (the black part in your eye's center) becomes larger than normal. This happens as a result of some medications and is a symptom of a concussion. Opthamologists (eye doctors) will use a certain kind of eyedrops to induce dilation to test if the eye is functioning properly.
well fat kids go poo then they sit on your eye and die

Yes you can, depending on the severity of your colorblindness. If you are mild red-green you should be able to tell basic colors apart. Except on the ishiAra colorblind test. There is a website that gives you the ishiAra slides and they can be memorized regardless of order that they are given. and most other colorblind tests can be memorized also unless your fully colorblind. As long as you can identify you primary colors an it doesn't affect your depth perception than it shouldn't be a problem. Good luck.
this part of the eye gets targeted for laser surgery because then the light can properly focus on the retina. hope this helps.
Highly unlikely. Eye color and color blindness are not determined the same way within your DNA. -Eye color depends on what color your eyes your parents have and the dominance of specific traits and alleles. -Color blindness is linked primarily to gender. It's a sex linked mutation and occurs only on the X chromosome. Males are much more likely to be color blind than females, because it is linked only to the x chromosome. Males only have one x chromosome and females have two. For females to have the colorblind mutation, their father has to be colorblind and their mother has to be a carrier or colorblind. For a male to be colorblind their mother has to either be a carrier or color blind. It is much more likely that mother is carrier than colorblind.
The iris is the coloured part of the eye.
the eye is part of a needle
