what is the difference between color blindness and night blindness? According to its pigments
@Rahul :- Your friends are right. However I will like to add some points.
In night blindness the rod cells present in the retina of eyes loses their ability to respond to light.
Colorblindness occurs due to deficiency of colour sensitive pigments in the cone cells of retina in eyes.
@Others :- Good effort, keep contributing !!
Night blindness refers to the inability of the eye to adapt to reduced illumination, therefore, leading to a complaint of not being able to see in the dark. Individuals suffering from night blindness not only see poorly at night but also require some time for their eyes to adjust from brightly lit areas to dim ones.
Colour blindness, on the other hand refers to the difficulty in seeing differences between some of the colors that other people can easily distinguish. It is most often genetic in nature, but might also occur because of the eye nerve, or brain damage or due to exposure to certain chemicals.
.Color blindness, or color vision deficiency, in humans is the inability to perceive differences between some or all colors that other people can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals. The English chemist John Dalton in 1794 published the first scientific paper on the subject, "Extraordinary facts relating to the vision of colors", after the realization of his own color blindness; because of Dalton's work, the condition is sometimes called Daltonism, although this term is now used for a type of color blindness called deuteranopia
Night blindness is the inability or reduced ability to see in dim light or in darkness. It also refers to the condition in which the time it takes for the eyes to adapt to darkness is prolonged.
