Study Summary
The goals of this study are to assess the short-term (10-60 minutes) effects of different magnitudes of myopic and hyperopic optical defocus on the transient thickness of the choroid in children and adults, as well as to assess the recovery period. Choroidal thickness will be measured non-invasively following 10-60 minutes of monocular exposure to -5 diopters to +5 diopters of optical defocus induced by spectacle lenses. The hypothesis is that choroidal thickness will increase with increasing myopic defocus and decrease with increasing hyperopic defocus. The relationship between the magnitude of defocus and the magnitude and direction of choroidal thickness change will be assessed.
