Myopia Focal Point Position

Myopia, also known as nearsightedness, happens when the eye's lens system focuses the image of distant objects in front of the retina. This results in blurry vision for objects that are far away.

Correcting Myopia with Lenses

To correct this condition, a lens is used that diverges light rays before they enter the eye. This type of lens is a concave lens.

The concave lens decreases the converging power of the eye's lens system, effectively shifting the focal point backward onto the retina. This allows for clear vision of distant objects.

Thus, the focal point in myopia falls in front of the retina, and correction is achieved using a concave lens.
