   Jul 16, 2020 · Photopsins are found in the cone cells of the eye and come in three types — red, blue and green.

   Sep 3, 2015 · Yes. In fact, photons are the only thing that humans can directly see. A photon is a bit of light. Human eyes are specifically designed to detect light. This happens when a photon enters the eye and is absorbed by one of the rod or cone cells that fill the retina on the inner back surface of the eye.

   At threshold sensitivity, the human eye can detect the presence of about 100-150 photons of blue-green light (500 nanometers) entering the pupil. For the upper seven decades of brightness, photopic vision predominates, and it is the retinal cones that are primarily responsible for photoreception.

   How does the human eye detect color?

   • The human eye is designed to detect the color, location, direction, and brightness patterns of a group of photons, but not the spin or wave phase. Color information is detected in the eye by having three different types of cone cells that each have a different range of color sensitivity.

   How can a human eye see a large object?

   • In broad daylight, humans can visualize objects in the glaring light from the sun, while at night large objects can be detected by starlight when the moon is dark. At threshold sensitivity, the human eye can detect the presence of about 100-150 photons of blue-green light (500 nanometers) entering the pupil.

   How do eyes work?

   • Your eyes work much like a camera. Light bounces off the image in front of you and comes into your eyes through the cornea. The cornea is a clear thin layer on the outside of your eyes. The cornea will help direct the light towards your pupil and Iris. These two parts work together to control the amount of light entering your eye.

   Jul 1, 2015 · This is like controlling the aperture of a camera. Once the light comes through the pupil it will go through the eye’s lens. Just like in a camera, the lens is used to focus on an object and direct the light to the back of the eye. The back of the eye is called the retina and it has special sensors called cones and rods.
