Why would having the whole retina in high resolution be problematic?
Why would having the whole retina in high resolution be problematic?
- Photoreceptors would lose sensitivity
- The blind spot would take up most of the retina (correct)
- It would require more energy to process information
- The optic nerve would be too small to carry all the information
