Answer:
the fact that rod functioning predominates during dark adaptation, therefore poor acuity
Explanation:
- Rods and cones are the photoreceptor cells present in the eye that perform the function of converting the light received into signals that stimulate the biological processes.
- Out of the rods and cones, the rods are more sensitive and they are so sensitive that they can be activated even under low light conditions.
- However the cones can be stimulated only under bright light conditions, but the visual acuity is higher for the cones as compared to the rods.
- <em>Therefore under conditions of dim light, the rods are activated and hence it results in a poor visual acuity and a person experiences difficulty in reading. </em>
