Question

The minimum distance at which the objects can be seen most distinctly without strain is called

• A. far point of the eye
• B. near point of the eye
• C. range of accommodation
• D. power of accommodation

Hint:

Remember the typical value of the near point for a normal human eye (around 25 cm) as the distance of distinct vision.

Answer 1

The Correct Option is B

Step 1: Understand the terms related to the eye's ability to focus.

• 
  Far point of the eye:
  This is the maximum distance at which an object can be seen clearly by the eye without any strain. For a normal eye, the far point is considered to be infinity.
• 
  Near point of the eye:
  This is the minimum distance at which an object can be seen clearly and distinctly without any strain. For a normal young adult, this distance is typically around 25 cm.
• 
  Range of accommodation:
  This is the distance between the near point and the far point of the eye. It represents the range over which the eye can focus clearly.
• 
  Power of accommodation:
  This is the ability of the eye to change the focal length of its lens to focus on objects at different distances. It is related to the action of the ciliary muscles.

Step 2: Identify the term that matches the definition given in the question.
The question asks for the minimum distance at which objects can be seen most distinctly without strain. This definition corresponds to the near point of the eye.
