Quizplus · Accepted Answer

When the human eyeball is too short from front to back, it results in hyperopia or farsightedness. This condition is corrected using convex lenses, which help focus the light more directly onto the retina. Convex-convex eyeglasses are designed with lenses that bulge outward, making them effective for this purpose.
