Aspect | Rods | Cones |
Presence in the Retina | More numerous (about 20 times more than cones) | Less numerous |
Location in the Retina | Predominantly in the peripheral regions of the retina | Concentrated in the central region of the retina (fovea) |
Sensitivity to Light | Highly sensitive to low light levels | Less sensitive to low light, more active in bright light |
Nature of vision | Scotopic vision | Photopic vision |
Function | Predominantly involved in peripheral and night vision | Predominantly responsible for central and color vision |
Visual Acuity | Lower visual acuity (less ability to discern fine details) | Higher visual acuity (better ability to discern fine details) |
Color Sensitivity | Mostly achromatic (sensitive to shades of light and dark) | Responsible for color vision (trichromatic vision) |
Pigment Type | Rhodopsin | Photopsin which is a visual pigments specific to different cones |
Adaptation to Bright Light | Slow adaptation | Rapid adaptation |
Recovery Time after Light Exposure | Have a longer recovery time after exposure to bright light | Shorter recovery time after exposure to bright light |
Role in Dim Light Conditions | Main photoreceptors in low-light conditions | Limited function in low-light conditions |
Role in Daylight Conditions | Less active in well-lit conditions | Main photoreceptors in well-lit conditions |
