What corrective lenses are typically required for myopia?

Myopia, commonly known as nearsightedness, is a refractive error where distant objects appear blurry while close objects can be seen clearly. This occurs when the shape of the eye causes light rays to focus in front of the retina rather than directly on it. To correct myopia, lenses are needed that can help adjust the focal point back onto the retina.

Minus corrective lenses, which have a concave shape, diverge light rays before they enter the eye. This adjustment effectively moves the focal point backward, allowing individuals with myopia to see distant objects more clearly. Therefore, minus corrective lenses are the standard prescription for individuals diagnosed with myopia, making them the appropriate choice for this condition.

In contrast, plus corrective lenses are used for hyperopia (farsightedness), while bifocal lenses are typically prescribed for presbyopia or for those who have both myopia and the need for reading correction. Not requiring lenses is not a practical option for someone with myopia, as corrective lenses are essential for restoring clear vision at a distance.
