How is eye color related to your vision?
In order to understand how eye color affects your vision, it will be helpful to understand how eye color develops. The iris is the colored part of the eye, and the amount of pigmentation within the iris determines your eye color. There are three genes that are responsible for determining the pigmentation.
How does the cornea control the color of the eye?
The cornea bends light toward the pupil, which controls the amount of light that hits the lens. The lens then focuses the light on the retina, the layer of nerve cells in the back of the eye. Cones Influence Color Perception Your retina has two different types of cells that detect and respond to light—rods and cones.
Which is the best test for color vision?
Color vision can be tested with standard pseudoisochromatic Ishihara or Hardy‐Rand‐Ritter plates, both of which contain numbers or geometrical shapes that the patient is asked to identify among different colored dots.2 Qualitative inter‐eye differences in color perception can be tested by comparing a red bottle top, for example, with each eye.
Which is part of the retina recognizes color?
These cones have light-sensitive pigments that enable us to recognize color. Found in the macula (the central part of the retina), each cone is sensitive to either red, green or blue light (long, medium or short wavelengths). The cones recognize these lights based on their wavelengths.

Which is part of the eye allows you to see?
The lens, retina and optic nerve are several important parts of your eye that allow you to transform light and electrical signals into images. What is vision? Your vision is what allows you to see the world around you. You have vision thanks to several components within the eye and brain that work together. These parts include the: Lens. Retina.
