Brain Activation Induced by Myopic and Hyperopic Defocus From Spectacles

Brain Activation Induced by Myopic and Hyperopic Defocus From Spectacles

Purpose: To assess neural changes in perceptual effects induced by myopic defocus and hyperopic defocus stimuli in ametropic and emmetropic subjects using functional magnetic resonance imaging (fMRI). Methods: This study included 41 subjects with a mean age of 26.0 ± 2.9 years. The mean spherical eq...
