Concave (diverging) lenses are fitted with glasses for nearsightedness (myopia). These lenses are thinner at the center and thicker at the edges, helping spread the light before it reaches the eye.
This adjustment lets distant objects focus properly on the retina, improving vision clarity.
An optometrist can determine the correct prescription to ensure clear and comfortable vision if you're nearsighted and looking for the right lenses.
