A
Feedback:
The contrast between object and background is one of the factors on which vision is dependent. The other factors are the size of the object, brightness (luminance), intensity of light and amount of reflection, and time allowed seeing the object. Protective outer layer of the eyeball, specific color of the eye, and nutrient and oxygen provided to the eye are not factors on which vision is dependent.
