Which type of lens is used to correct myopia?

• A. Concave lenses
• B. Convex lenses
• C. Intraocular lens
• D. Ocular prosthesis

Answer: (A)

Myopia is corrected with a lens that diverges light so the image can land on the retina. Distant objects appear blurry because the eye focuses images in front of the retina. A concave (diverging) lens spreads incoming light slightly, reducing the eye’s overall converging power and shifting the focal point backward onto the retina, making distant vision clearer. Convex lenses would converge light more, which helps hyperopia, not myopia. An intraocular lens is a surgical implant, and an ocular prosthesis is for cosmetic replacement, not typical vision correction.
