Long-sight defect means difficulty in focusing on distant objects which in other words is called shortsightedness (meaning you can see close by objects), this defect is known as myopia and myopia is corrected using concave lens,,, plz correct the question by replacing long-sight defect to shortsightedness/myopia or if you want to keep the question same then change the correct the answer

Concave Lens is used for long sight defect. So the answer is wrong.
Yes Shan bro, you are right.
Shortsightedness is corrected using a concave (curved inwards) lens which is placed in front of a myopic eye, moving the image back to the retina and making it clearer. Longsightedness is corrected using a convex (outward facing) lens.
Admin correct it , its ans is concave lens
Long-Sightedness (Short-Sight Defect) is corrected by Convex Lens and Short-Sightedness (Long-Sight Defect) is corrected by Concave Lens.
So, Correct Option is A.
Kindly update , it’s concave lens use to see distant object
