Rates of childhood myopia progression with bifocals as a function of nearpoint phoria: consistency of three studies

Optom Vis Sci. 1990 Aug;67(8):637-40. doi: 10.1097/00006324-199008000-00015.


Three studies on the effect of bifocal lenses on childhood myopia progression are discussed and re-analyzed. In all three, the rates of progression were less with bifocals than with single-vision lenses in esophoria. Rates with the two types of correction were similar in patients who had nearpoint orthophoria or exophoria.
