Nearsightedness HTML5

Pedagogical animation of the myopic (nearsighted) eye. Myopia is a condition where the eye is too long in relation to its refractive power. The light rays thus intersect, forming an image, in front of the retina. Notice that nearsighted people typically see well up close, but have difficulty seeing far away.
The corrective lens modifies the focal length to shift the point of intersection to the surface of the retina. We also show that correction moves the "near point" away from the eye.
