Optometry Fog As The Principle

Mist method is by adding the right amount of balls mirrors (myopia may also reduce negative spherical mirror) method into the light in the eyes of the focus comes together in front of the retina, to artificial myopia status (as shown in Figure 1), to relax regulation purposes. Fog conditions, patients if regulation, the focus will be more far away from the retina, the image will become ever more blurred, so its no longer use throttling. And if they want to see the sign in the distance, will be forcing yourself to relax regulation, only in the case of relaxed regulation will focus closer to the retina, and make the image more clearly. Human eyes have a tendency to clear the object, so in this case seized naturally relaxed regulation makes the image more clear, so as to achieve the objective of fog.
