Above the cones (sensitive to red, green, and blue light waves) that are in the yellow spot or fovea (that is where the light waves merge into a point). So we can see clearly. Do the neurons that are connected to it move to the side. So that the light can fall on it as much as possible. Each cone has only 1 neuron tower above it. So that the brain can figure it out and it can beautifully present us with the colors of the objects we see.

This is not the case with the sticks. They therefore take over the work of the cones when it is dusk or moon/dark. The rods are in contact with hundreds, sometimes thousands, of different neurons. The brain can no longer derive colors from that. That's why we see everything black, gray or white in the dark.

However, the rods are also sensitive to the medium green light waves.

Depending on what they want to transmit, the rods and cones in the eye have one or more connections with the neurons


The various neurons, such as the bipolar cells (orange on the sketch), the horizontal brown cells, and the yellow amacrine cells, have also captured the light that passed them and are transmitting their own additional findings to the beautiful round blue gangion cells in front. As a result of their structure, they have very long shoots that disappear into a tunnel, namely into the optic nerve. These cables transmit all the information about what you see to your brain. Where the optic nerve is, you can't see anything at all. Because that's where the blind spot is.
