By middle age, most people have age-related declines in near vision requiring bifocals or reading glasses. An emerging technique called hyperopic orthokeratology may provide a new alternative for restoring near vision without the need for glasses, according to a study, "Refractive Changes from Hyperopic Orthokeratology Monovision in Presbyopes," appearing in the Apr. issue of Optometry and Vision Science, official journal of the American Academy of Optometry.
