Eyeglasses to maintain flexibility of vision for the older dentist: the Otago dental lookover.

Presbyopia is inability of the eye to accommodate and provide clear images of near objects. It affects all dentists in middle age, when "near point," the nearest point at which the eye can focus accurately, exceeds ideal working distance. Dentistry has unique visual demands and many older dentists have been shown to be working with less-than-optimal visual efficiency and comfort. This paper discusses methods for improving vision in the dental operatory and details a new design for eyeglasses suitable for the presbyopic dentist.
