The effect of hypnotic suggestion on unaided visual acuity

8 February 1980


The effect of hypnotic suggestion and relaxation on myopic subjects' unaided visual acuity was assessed. Three groups, one control and two experimental, consisting of myopes of similar refractive error and hypnotic suggestibility, were evaluated. All groups showed significant levels of visual acuity improvement within themselves. Hypnotic (suggestive) relaxation used in experimental group 1 and experimental group 2 yielded a significant increase in acuity over the control. Specific hypnotic suggestion of improved vision used in experimental group 2 only had no significant effect on acuity. Monitoring of the refractive state of all subjects was done to assure that optical changes could not be used as an explanation for the post-induction acuity increases. The relevance of these findings to both patient and practitioner is discussed. Pertinent literature is reviewed.
