Optometrist prescribes contact lenses that have focal length

Reference no: EM13656764

An optometrist prescribes contact lenses that have a focal length of 56.0 cm. Where is the unaided near point of the person located, if the lenses are designed so that objects no closer than 32.0 cm can be observed clearly?
