The value of least distance vision for a normal eye is:
- A
20 cm
- B
30cm
- C
25cm
- D
40cm
This option suggests that the least distance of distinct vision for a normal eye is 25 cm. This is the correct value. The least distance of distinct vision refers to the minimum distance at which the human eye can focus on an object and see it clearly without any strain.
This option suggests that the least distance of distinct vision for a normal eye is 20 cm. However, this is not the correct value.
This option suggests that the least distance of distinct vision for a normal eye is 30 cm. However, this is not the correct value.
