Which types of lenses are used to correct hyperopia, myopia, and astigmatism respectively?

The correct answer identifies the appropriate lens types used in optical correction for different vision conditions. Hyperopia, commonly known as farsightedness, is effectively corrected using convex lenses. These lenses are thicker in the center and help to converge light rays, making it easier for the eye to focus on nearby objects.

For myopia, or nearsightedness, the correction is achieved with concave lenses. These lenses are thinner in the center and diverge light rays, allowing the eye to better focus on distant objects.

Astigmatism, which is caused by an irregular shape of the cornea or lens that leads to distorted vision, requires cylindrical lenses for correction. These lenses compensate for the uneven curvature of the eye, allowing for a more accurate refraction of light and improving clarity of vision.

Therefore, the combination presented in the answer – convex for hyperopia, concave for myopia, and cylindrical for astigmatism – correctly aligns with standard practices in vision correction.
