Distinguish between : Near point and Far point
| Near point | Far point | ||
| $1$. | The minimum distance at which the object can be seen clearly without contraction of eye lens is called the near point of an eye. | $1$. | The farthest distance upto which the eye can see objects clearly is called far point of an eye. |
| $2$. | For young adult with normal vision, this value is 25 cm. | $2$. | For young adult with normal vision, this value is infinite. |
| $૩$. | For a person having defect of far-sightedness value of the near point is at a distance more than 25 cm. | $3$. | For a person having defect of near-sightedness value of the far point is at a distance less than infinite distance. |
| $4$. | For a person having defect of far-sightedness value of the near point is obtained at a distance of 25 cm using convex lens of appropriate focal length. | $4$. | For a person having defect of near-sightedness value of the far point is obtained at distance of infinite distance using concave lens of appropriate focal length. |
