Fig. 3From: Peripheral refraction of myopic eyes with spectacle lenses correction and lens free emmetropes during accommodationMean profiles of central and off-axis refraction in terms of sphere (a and b) and spherical equivalent (c and d) for myopic eyes with spectacle lenses and lens-free emmetropic patients at each fixation distance. All data have been normalized by subtracting the central value at each fixation distance to the remaining respective off-axis values to highlight the different profiles at each given accommodative level. Error bars have been omitted for clarity. *Statistically significant differences for vergenceBack to article page
