Where can a far-sighted vision defective person place a reading material from the eyes for comfortable reading? Correct Answer Beyond 25 cm
The correct answer is Beyond 25 cm.
Key Points
- Hypermetropia is a defect of vision that causes the impossibility for rays of light to be focused on the retina but behind it.
- It is caused by light not being correctly focused, with light traveling behind the retina.
- People with hypermetropia can focus only on far objects, relying on accommodation, that is the lens contraction performed by the ciliary muscle.
- It is corrected with converging or positive lenses (convex lenses).
- The near-point of a hypermetropic eye is more than 25 cm away. Hence, a far-sighted vision defective person place a reading material beyond 25 cm from the eyes for comfortable reading
