What method is used for high-intensity light vision?

The correct answer is cones, which are specialized photoreceptor cells located in the retina of the eye. Cones are responsible for color vision and are highly effective in bright light conditions, allowing humans to see fine details and a broad spectrum of colors. They operate best under high-intensity light, making them essential for activities that require acute vision, such as reading or recognizing faces during the daytime.

Rods, in contrast, are more sensitive to low light and are responsible for night vision but do not perceive color. Photoreceptors is a broad term that encompasses both rods and cones, but it doesn’t specifically refer to the type that functions best in high light. Pupils control how much light enters the eye, but they do not directly involve the process of vision. Understanding the unique functions of cones helps clarify why they are the correct choice for high-intensity light vision.
