what leads to color blindness

Detailed explanation-1: -Your retina is made up of light-sensitive cells which send messages to your brain about what you see. Everyone has a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can’t see. We call this the blind spot.
Detailed explanation-2: -The blind spot is a region at the back of the eye where the optic nerve exits the eye on its way to the brain. At this spot, no image is formed due to the absence of photoreceptor cells, i.e. rods and cones.
Detailed explanation-3: -Everyone has a spot in the retina where the optic nerve connects. In this area, there are no light sensitive cells, so this part of your retina cannot see. We call this the blind spot. Your blind spot is not usually noticeable because your two eyes work together to cover up each eye’s blind spot.
Detailed explanation-4: -The part of the eye that is the “blind spot” is the D) optic disc. The optic disc is the head of the optic nerve. This is where the ganglion cell axons exit the eye to form the optic nerve but because there are no rods or cones present, this causes a break in the visual field that is called the “blind spot".
Detailed explanation-5: -Located in the middle cranial fossa is the optic chiasm. The optic nerves of both eyes meet at the optic chiasm and form the optic tracts.
