Vision Simulator
This tool simulates how an eye focuses an image and how glasses can correct vision. A positive (+) inherent error represents Myopia (short-sightedness), and a negative (-) inherent error represents Hyperopia (long-sightedness).
Eye & Object Configuration:
E.g., +2.0 for 2D Myopia, -1.5 for 1.5D Hyperopia.

Shows the eye's vision without any correction. Notice how an error results in a blurry image.
Simulates wearing glasses. A correct prescription (-1 * error) should produce a sharp image.
