Just a little shot, really. But first, it's worth understanding how we see regular colors in the first place. Humans have two types of cells in their eyes to help them see: rods and cones.

The key retina parts include the rods and cones, which convert light into electrical signals for the brain, and the macula, which allows you to see details clearly.

However, your eyes perform less impressively in low light. Human eyes contain two types of cells that respond to light — rods and cones. Rods are numerous and much more sensitive to light.

Instead the result is a sort of hybrid vision in which the eyes can perceive only some colors. "Rods and cones don't have separate signal pathways to the brain," Neitz says.

Cone-rod dystrophy is a group of IRDs that damage cones and rods. Vision loss gets worse over time. Between 1 in 30,000 and 1 in 40,000 people have cone-rod dystrophy.

The A-wave is a positive wave that mainly originates from the cornea of the eye, while the B-wave is a negative wave that represents the electrical response of the retina's rods and cones to light.

From inside our own eyes. Eyes are amazing organs, and very complex, but when it comes to transmitting what we see outside into the brain, it relies on two types of cells – rods and cones.

The eyes are complex organs. In this article, we look at their anatomy and how they work, and we describe some conditions that affect the eyes.

Researchers observed light response in four out of four cones in mice that were 3.5 weeks old as well as 7 of 10 cones in mice that were 6 weeks old and 1 out of 3 cones at 9 weeks old.
