The minimum distance from the eye at which an object can be seen clearly without strain is called:
Correct answer: B. Near point
- A. Focal point
- B. Near point
- C. Yield point
- D. Far point
Explanation
The near point is the minimum distance from the eye at which an object can be seen clearly without strain. It is also known as the closest point of clear vision. As we age, the flexibility of the lens in the eye decreases, causing a decrease in the near point.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
