11
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.
12
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.
13
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.
14
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.
15
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.
16
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.
17
_____ lenses are used by people suffering from myopia.
RRB Group-D
04/10/2018 / Shift-II
2018
✓ Answer:CConcave
Concave lenses are used to correct myopia by diverging incoming light so the eye focuses distant objects on the retina.
18
A disorder in which a person cannot see a distant object clearly is called:
RRB NTPC (Stage-I)
11/04/2016 / Shift-III
2016
✓ Answer:CMyopia
Myopia, or nearsightedness, makes distant objects appear blurred while nearby objects remain clear. It is corrected using a concave lens. Option D is retained as printed in the source.
19
Nearsightedness is termed as?
✓ Answer:BMyopia
Nearsightedness is another name for myopia. In this condition, nearby objects are seen clearly while distant objects appear blurred. A concave lens is used for correction.
20
In which light produces image focus in front of the retina?
✓ Answer:DMyopia
In myopia, the image of a distant object is formed in front of the retina because of excessive converging power or an elongated eyeball. A suitable concave lens corrects the defect.
