What type of receptors in the retina are sensitive to light?

Rods are specialized photoreceptor cells located in the retina that are highly sensitive to light, making them essential for night vision and low-light conditions. They contain a photopigment called rhodopsin, which is particularly effective at absorbing photons of light, allowing rods to function well in dim environments. This sensitivity allows them to detect various degrees of brightness, contributing to our ability to see in low-light situations.

In contrast, while cones also serve as photoreceptors and are responsible for color vision and visual acuity in well-lit conditions, they are less sensitive to light than rods. There are three types of cone cells, each sensitive to different wavelengths, which facilitate the perception of colors. However, rods dominate in scenarios involving minimal light. Therefore, when considering which receptors in the retina are primarily sensitive to light, rods are the clear answer.
