Figure 1.

Interocular differences in refractive error (treated eye correction−fellow eye correction) plotted as a function of age for individual monkeys reared with −3D (left panel) or +3D lenses over one eye (middle panel).^{22, 46} The fellow eyes viewed through zero-powered lenses. The first symbol represents the start of the lens-rearing period. The shaded regions indicate ±2 SD around the mean anisometropia for untreated control monkeys. The right panel illustrates the interocular difference in refractive error (distance corrected eye−near corrected eye) as a function of time for children corrected using a monovision strategy that imposed up to 2.0 D of relative hyperopia on the near corrected eye.⁴³
