Abstract

Purpose : New spectacle lenses with concentric rings of contiguous aspherical lenslets have shown promising effects for myopia control. The purpose of the study was to evaluate peripheral visual performance through these lenses using psychophysical tasks.

Methods : Two types of experimental lenses were used - spectacle lenses with highly aspherical lenslets (HAL) and spectacle lenses with slightly aspherical lenslets (SAL) arranged in concentric rings in both lenses. A standard plano single vision lens was used as a control. We tested three visual functions consisting of motion detection (phase-shifting gabor), coherent motion direction discrimination (random dot kinematogram), and useful field of view (UFOV™, Posit Science®, United States). Each function was tested on a sample of 10 adults (mean age: 30.5, 26.3, 33.7 years, age range 20-37,19-49, 26-49 years, for the three functions respectively). All subjects had normal or corrected-to-normal vision and all tests were done monocularly using their dominant eyes.

Results : No significant difference between the test lenses and control was found in any test. Specifically, the motion detection threshold was not affected by the lens in any quadrant of the visual field (one-way ANOVA, p > 0.7). For global motion direction discrimination, a two-way ANOVA found no significant effect of the lens (p = 0.87) on the coherence threshold in any direction. In the useful field of view test, one-way ANOVAs showed no significant effect of the lens on visual detection in the whole visual field (p > 0.5).

Conclusions : Myopia control lenses with concentric rings of contiguous aspherical lenslets (HAL and SAL) did not significantly impact peripheral visual functions including motion detection, coherent motion direction discrimination, and useful field of view, compared to single vision lenses.
