¿Por qué no podemos ver en la oscuridad?<end_of_turn>
<start_of_turn>model
A human being is endowed with five natural senses: touch, hearing, smell, taste and sight. Each sense has specific ways to make us feel. As for sight, for example, when there is light, we see very well, when our eyes are in good health of course.

The eye is made up of different cells including rod cells and cone cells. Each type of cell has a specific role. Rod cells, for example, allow us to see light or anything that is illuminated. As for cone cells, they allow us to distinguish colors. These cells are found in the fovea area behind the eye.

On the other hand, the rod cells take up all the remaining space.
When we are faced with very bright light, the pupil narrows so that the light does not hit our eye. On the other hand, if we are in the dark, the pupil dilates to let in the little light that is in the eye.

This small amount activates the rod cells and we can see in the dark. However, the dilation of the pupils is at its limits. If there is not enough light to pass through to activate the rod cells, then we cannot see in the dark.<end_of_turn><eos>
