The correct Answer is:
D
far-sighted (Adjective) : long-sighted , not able to see things clearly that are close to you
myopic (Adjective) : inability to focus on distant objects, short- sighted
short-sighted (Adjective) : able to see things clearly only if they are very close to you
feeble-minded (Adjective) : having less than usual intelligence , weak and unable to make decisions
fore-sighted (Adjective) : planning sensibly and carefully for the future
myopic (Adjective) : inability to focus on distant objects, short- sighted

Statement I : A myopic person is advised to use concave lens. Statement II : The eye lens of a myopic person focuses the parallel rays coming from distant ogject in from distant objects in front of the retina.
The for point of a myopic person is 80 cm in front of the eye. What is the power of the lens required to enable him to see very distant objects clearly? In what way does the corrective lens help the above person? Does the lens magnify very distant object? Explain.
(a) The far point of a myopic person is 80 cm . In front of the eye. What is the power of the lens required to enable him to see very distant objects clearly ? (b) In what way does the corrective lens help the person above ? Does the lens magnify very distant objects ? Explain carefully. ( c) The person above prefers to remove his spectacles while reading a book. Explain why ?
(a) Draw a diagram to show the formation of image of a distant object by a myopic eye. How can such an eye defect be remedied ? (b) State two reasons due to which this eye defect may be caused. ( c) A person with myopic eye cannot see objects beyond a distance of 1.5 m . What would be the power of the corrective lens used to restore proper vision ?
Assertion : Concave lens is used to correct myopia or short-sightedness. Reason : A concave lens of suitable focal length diverges the parallel rays from the distant objects as if they are coming from the far point of the myopic eye. This helps the eye lens to form a clear image at the retina.
Being myopic, the far point for the left eye of a person has shifted to 1.5 metre while being hypermetropic, the near point for his right eye has shifted to 0.50 metre. Find the powers of the lenses used for the corrections.
