How do individuals with short sightedness correct their vision?

Individuals with short sightedness, also known as myopia, typically have difficulty seeing distant objects clearly while they can see nearby objects without issue. This condition occurs because the eye focuses light in front of the retina rather than directly on it. To correct their vision, individuals with short sightedness use concave lenses.

Concave lenses are thinner in the center and thicker at the edges. When these lenses are placed in front of the eyes, they diverge light rays before they enter the eye, effectively moving the focal point back to the retina. This allows the person to see distant objects more clearly.

In contrast, convex lenses, which are thicker in the center and thinner at the edges, would be used for correcting far-sightedness (hyperopia), where individuals struggle to see close objects. Eye drops and laser surgery are not primary means of correcting short sightedness; they serve different purposes in eye care. Eye drops can be used for various conditions, and laser surgery typically reshapes the cornea to improve vision but is not the only solution for myopia correction. Hence, the use of concave lenses is the correct method for correcting short sightedness.
