To investigate how age affects peripheral refraction we measured objective peripheral refraction for 55 young subjects (24 ± 4 years) and 41 older subjects (59 ± 3 years) out to 35°eccentricity in temporal and nasal visual fields. Subjects were compared in 1 D subgroups based on central spherical equivalent refractions (low hypermetropes +0.54 D to +1.51 D, emmetropes +0.50 D to À0.49 D, low myopes À0.50 D to À1.49 D, moderate myopes À1.50 D to À2.58 D). Overall, young and older subjects with

Both age groups showed relative hypermetropic shifts in the peripheral fields as myopia increased and also decreases in peripheral astigmatism J 180 as myopia increased. J 45 varied little across the visual field with linear relationships occurring between J 45 and visual field angle for all but one subgroup (older emmetropes). Peripheral refraction in emmetropes to moderate myopes is relatively unaffected by age for healthy eyes of similar refractive errors.
