What is the Scotopic vision ?
Scotopic vision refers to the ability to see in low light conditions, using the rod cells in the retina. It is also known as night vision.
Characteristics of scotopic vision:
1. Low light sensitivity : Rod cells are more sensitive to low light levels than cone cells.
2. Black and white vision : Scotopic vision is monochromatic, meaning it sees only shades of gray.
3. Peripheral vision: Rod cells are concentrated in the periphery of the retina, making scotopic vision better for detecting motion and seeing in the periphery.
4. Slower adaptation : Scotopic vision takes longer to adapt to changes in light levels compared to photopic vision.
Scotopic vision is essential for:
1. Night driving
2. Navigating in dimly environments
3. Detecting movement in low light Factors that can affect scotopic vision:
1. Age : Scotopic vision declines with age.
2. Eye diseases : Certain conditions, such as retinitis pigmentosa, can affect scotopic vision.
3. Nutritional deficiencies : Lack of vitamin A can impair scotopic vision.
Scotopic vision is the ability to see in low light conditions, using the rod cells in the retina, and is essential for navigating and detecting movement in dimly lit environments.
