- Light receptors in the eye
- Rod cells
- More than cone cells
- More in the periphery of the retina and none at the fovea
- Poor visual acuity
- Sensitive to low intensity light
- Rhodopsin sufficiently broken down by low-intensity light.
- Rhodopsin sufficiently broken down by low-intensity light.
- Three cells linked to one neurone
- Poor visual acuity
- Cone cells
- Less than rod cells
- Concentrated at the fovea and fewer at the periphery of the retina
- One neurone linked to one cell
- High visual acuity
- One neurone linked to one cell
- Not sensitive to low-intensity light
- A higher light intensity is required to breakdown iodopsin.
- Not sensitive to low-intensity light
- Rod cells
