What are the three types of vision according to light conditions?

The three types of vision according to light conditions are described as photopic, mesopic, and scotopic.

Photopic vision occurs under well-lit conditions, primarily relying on cone cells in the retina that are responsible for color vision and detail. This type of vision is dominant during the day and in bright environments.

Mesopic vision is experienced in transitional light conditions, such as twilight, where both cone and rod cells contribute to vision. This type of vision helps in low-light scenarios where some light is still present, allowing for a balance of color recognition and sensitivity to movement.

Scotopic vision operates under very low light conditions and is primarily dependent on rod cells, which are more sensitive to light but do not provide color perception. This type of vision is crucial for seeing in darkness or very dim environments.

The other options do not categorize vision based on specific biological mechanisms related to varying light conditions. For example, color, grayscale, and monochrome refer to types of images rather than the physiological adaptations of vision according to light levels. Similarly, descriptors like bright, dim, and dark are qualitative rather than scientific classifications of how our vision operates under different lighting conditions.
