If a person can see distant objects clearly but cannot see nearby objects clearly, this eye defect can be corrected by using:
RRB ALP (Stage-I)
26/11/2024 / Shift-III
2024
✓ Answer:CA convex lens of appropriate power
The defect is hypermetropia. A convex lens of appropriate power converges incoming light so that the image of a nearby object is focused on the retina.
522
The problem of nearsightedness (myopia) in the human eye can be corrected by using which of the following?
A concave lens diverges incoming light and allows the myopic eye to focus the image of a distant object on the retina.
523
In a normal eye, the distance of the retina from the eye lens is 2.5 cm. What is the power of the eye lens when it is focused at its near point, 25 cm from the eye?
RRB Group-D
30/09/2022 / Shift-II
2022
✓ Answer:B44 D
Using the lens formula with u = -0.25 m and v = 0.025 m: P = 1/f = 1/v - 1/u = 40 - (-4) = 44 D.
524
A lens of power 8 D is kept in contact with another lens of power -4 D. The lens combination will act as a:
RRB Group-D
26/08/2022 / Shift-III
2022
✓ Answer:BConvex lens with focal length 25 cm
For lenses in contact, powers add: P = 8 + (-4) = +4 D. Hence f = 1/P = 0.25 m = 25 cm. Positive power means the combination acts as a convex lens.
525
Light enters the eye through the _____.
RRB NTPC (Stage-I)
03/04/2021 / Shift-II
2021
✓ Answer:BCornea
Light first passes through the cornea, the transparent front surface of the eye, which helps refract incoming light.
526
Short-sightedness is also called _____.
RRB NTPC (Stage-I)
08/04/2021 / Shift-II
2021
✓ Answer:BMyopia
Short-sightedness is myopia. Distant objects appear blurred because their images are focused in front of the retina.
527
For a person with hypermetropia or farsightedness, the near point is _____ farther away from the normal near point.
RRB NTPC (Stage-I)
07/03/2021 / Shift-I
2021
✓ Answer:C25 cm
The source key selects 25 cm, but the wording is incorrect. The normal near point is about 25 cm from the eye; in hypermetropia, the near point lies beyond this distance, not necessarily 25 cm farther away. The source key is retained.
528
The _____ oval spot in the human eye is the area of best vision.
RRB NTPC (Stage-I)
16/02/2021 / Shift-II
2021
✓ Answer:AYellow
The yellow spot, or macula, is near the centre of the retina. Its central fovea has a high density of cones and provides the sharpest vision.
529
The ability of the eye to focus on both near and distant objects by adjusting its focal length is called the _____ of the eye.
RRB NTPC (Stage-I)
11/01/2021 / Shift-I
2021
✓ Answer:CAccommodation
Accommodation is the ability of the eye to adjust the focal length of its lens to focus on objects at different distances.
530
Nearsightedness in humans is called:
RRB NTPC (Stage-I)
18/01/2021 / Shift-I
2021
✓ Answer:AMyopia
Myopia is nearsightedness. A person sees nearby objects clearly but has difficulty seeing distant objects clearly.
