Fovea centralis of retina is the place of formation of sharpest vision where --------------
- Aonly rods are present.
- Correct answerBonly cones are present.
- Cboth rods and cones are present.
- Dboth rods and cones are absent.
Solution
The fovea centralis is a thinned-out portion of the retina located in the centre of the macula lutea.
It contains a very high density of cone cells, which are responsible for colour vision and high visual acuity in bright light.
Rod cells, which are responsible for vision in dim light, are completely absent in this region.
Due to the dense packing of only cone cells, the fovea centralis is the point of sharpest vision (greatest visual acuity) in the eye.
Answer: only cones are present.
