Purpose.

To determine the impact of wearing single-vision spectacle lenses (SVLs) on the refractive errors at the periphery of the retina in myopic eyes of Chinese children.

Methods.

Twenty-eight children (8 to 15 years) were divided into two groups: one (n= 17) comprising children with low myopia (spherical equivalent between− 0.75 D and− 3.00 D inclusive) and the other (n= 11), with moderate myopia (spherical equivalent between− 3.25 D and− 6.00 D inclusive). Cycloplegic autorefraction from right eyes was measured at the fovea and at 20, 30, and 40 in the temporal and nasal visual fields. Measurements were taken on each subject both while uncorrected and while wearing SVLs.

Results.

Hyperopic peripheral defocus was found with SVLs in both the low and moderate myopia groups. However, the increase in relative peripheral hyperopic defocus when wearing spectacle correction, when compared with the …
