Difference Between Rods and Cones
The Difference Between Rods and Cones are given below:
| Features | Rods | Cones |
|---|---|---|
| Shape | Rods are long and slender | Cones are short and tapered |
| Quantity | There are approximately 120 million rods | There are approximately 6 to 7 million cones. |
| Location | Rods are concentrated in the peripheral retina | Cones are mostly concentrated in the fovea (centre of the retina) |
| Sensitivity | Rods have high sensitivity to light (function well in low-light conditions) | Cones have lower sensitivity to light (function well in well-lit conditions) |
| Vision Type | They provide black-and-white vision | They provide colour vision (sensitive to red, green, and blue light wavelengths) |
| Function | Rods aid in the night and peripheral vision | Cones aid in Daytime and colour vision |
| Visual Acuity | Visual acuity of rods is low | Visual acuity of cones is high |
| Photopigments | The photopigment in rods is rhodopsin | The photopigment in rods is Iodopsin |
| Response Time | Response time of rods is slow | Response time of rods is fast |
Difference Between Rods and Cones
The difference between rods and cons lies in their functions and distribution within the retina. The rods and cones are two different kinds of photoreceptors present in the retina. Rods are more sensitive to low light and are primarily responsible for night vision, while cones are responsible for colour vision and function best in bright light conditions. In this article, we will cover the major differences between rods and cons and their similarities.
