    Patent number: 8967797
    Abstract: Adjustable focus eyeglasses where the range of adjustment can be moved. That is, if a pair of adjustable focus eyeglasses have a range of 0 diopters to 2.75 diopters (to provide a 2.75 D ADD for reading for an emmetrope), this invention could, for example, permit the user to move the range from 0 D to 2.75 D to 2.00 D to 4.75 D so as to accommodate a short term change in the user's distance vision requirement. Each eye can be adjusted independently.
