How Does Your Eye Ignore The Center of an Annular Multifocal Lens?
When you are wearing bifocal glasses or contacts, when you look down, you are looking through the part of the lens meant for reading. The distance part of the lens is out of your visual field.
With annular multifocal, the distance and close lenses are in rings, like a target. If there's a simple answer, I'd like to know how you eye can ignore the center portion of the annular design. I understand it can be either distance or reading. How can your eyes see things in the distance if the reading part of the lens is right smack in the middle of your field of vision?
