_____ lenses are used by people suffering from myopia.
RRB Group-D

✓ Answer:CConcave
Concave lenses are used to correct myopia by diverging incoming light so the eye focuses distant objects on the retina.
532
What is the nature of the image that is formed on the retina of human eye?
✓ Answer:DReal and inverted
The eye's optical system forms a real and inverted image on the retina. The brain interprets the visual information so that we perceive the object in its proper orientation.
533
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.
534
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.
535
Ability of the eye lens to change its focal length to see objects placed at different places is called:
✓ Answer:BPower of Accommodation
The ability of the eye lens to change its focal length according to the distance of the object is called power of accommodation. Ciliary muscles change the curvature of the lens to focus near and distant objects clearly on the retina.
536
Human eye has a near point i.e. distance of distinct vision at approximately 25 cm. For a normal eye, which of the following statements is true?
✓ Answer:BThe image formed on the retina is real, inverted and diminished.
The convex eye lens forms a real, inverted and diminished image on the retina. The brain processes this image so that we perceive objects correctly.
537
In which light produces image focus in front of the retina? Additional option E: None of the above.
✓ Answer:AMyopia
In myopia (short-sightedness), the image of a distant object is formed in front of the retina. It can occur when the eyeball is elongated or the converging power of the eye is too high. A concave lens is used for correction. The supplied question has five options; option E is preserved in question_text because this CSV has four option columns.
538
Near-sightedness can be corrected using:
✓ Answer:CConcave lens
Near-sightedness is called myopia. In myopia, light focuses in front of the retina. A concave lens diverges the incoming rays so that the image is shifted back onto the retina.
539
Far-sightedness can be corrected using:
✓ Answer:DConvex lens
Far-sightedness, or hyperopia, occurs when light would focus behind the retina. A convex lens converges the rays before they enter the eye and helps form the image on the retina.
540
Colour vision in human eyes is the function of photoreceptor cells named:
✓ Answer:BCones
Cone cells are photoreceptors responsible mainly for colour vision and detailed vision in bright light. Rods are mainly responsible for vision in dim light.
