Popular claims about eye exercises, and what eye care organisations say about them.
Eye exercises cannot replace glasses or reverse nearsightedness, farsightedness, astigmatism or presbyopia. The American Academy of Ophthalmology says there is no convincing evidence that exercises, palming or the Bates method improve uncorrected eyesight.
