Question

What are the near and far points of a healthy human eye?

Answer 1

1. A specialized sense organ capable of receiving visual images, which are then carried to the brain is known as the eye.
2. The average value of the least distance for a clear vision for a normal eye is $25\mathrm{cm}$ and the maximum distance is infinity.

Therefore, $25\mathrm{cm}$ to infinity are the near and far points of a healthy human eye.
