Question 1 Report
Which of the following is used for the correction of short sightedness?
Answer Details
Short-sightedness, also known as myopia, is a condition where a person is able to see nearby objects clearly but distant objects appear blurry. It is caused by an elongated eyeball or a misshapen cornea, which causes the light entering the eye to focus in front of the retina instead of on it. To correct myopia, a concave lens is used. A concave lens is thinner at the center than at the edges, which causes the light entering the eye to diverge before it reaches the cornea, allowing the image to focus correctly on the retina. Therefore, the correct answer is concave lens.
