  A computer program that tests peoples eyes to find their eyeglass prescription. It could duplicate the effects of the machine with the lenses that the optometrist makes you look through. The person would look at the computer screen without any glasses on and select which of two images looks clearer repeatedly, just like at the optometrist. The computer program would emulate the effect of an eyeglass lens. The image would look like what a person with perfect vision would see if he put on someones eyeglasses. Of course to someone who needed that eyeglass prescription, the image would look clear. This system would save money because you would not need the expensive equipment at the optometrist, and people could test themselves at home to make sure that they had the best eyeglass prescription.
