Fig. 8From: How does the world appear to patients with multifocal intraocular lenses?: a mobile model eye experimentLight energy distribution at near and far distances. If 30% of the light energy goes to the near focus and 70% of the light energy goes to the far focus, the halo will be strong at the near distance, but will be weak at the far distance (a). Conversely, if 70% of the light energy goes to the near focus and 30% goes to the far focus, the halo will be weak at the near distance, but will be strong at the far distance (b) (This figure was created by Ho Sik Hwang)Back to article page
