The normal human eye can focus a sharp image of an object on the eye if the object is located at certain distance called:
Correct answer: B. Near Point
- A. Least Point
- B. Near Point
- C. Far Point
- D. Distinct Point
Explanation
Near point is the point nearest the eye at which an object is accurately focused on the retina at full accommodation, making a sharp image.

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.
