Full Diameter Telescopes (Galilean Telescopes) are designed for distance tasks that are to be performed while the patient is stationary. Mobility is not practical, since walking with Full Diameter Telescopes would be analogous to walking while looking through a pair of binoculars. These telescopes are especially suited for such distance tasks as watching T.V., going to the Theater, sporting events, or spotting distance stock market quotations – anything that can be done while the patient is stationary.
