New research from SightGlass Vision found children wearing Diffusion Optics Technology (DOT) spectacle lenses for myopia control displayed viewing behavior and performance comparable to children wearing standard single-vision lenses during a range of everyday activities.
The findings, presented at the American Academy of Optometry 2026 Annual Meeting in Anaheim, Calif., come from four studies examining children’s experiences with DOT lenses, including eye and head movements, performance during dynamic activities, quality of vision, and overall satisfaction.
DOT lenses provide myopia control by using light-scattering elements to reduce retinal contrast signaling while maintaining a single power across the lens. The lenses are not currently available in the United States.
Evaluating Everyday Activities
In one study, researchers used eye tracking to compare children wearing DOT and single-vision lenses while reading, gaming, watching a lecture, and walking. Eye and head movements remained consistent between groups, with no evidence that children altered their gaze or head position to compensate for DOT lenses.
A second study used immersive motion capture while children located peripheral targets, caught virtual baseballs, and navigated a bicycle around obstacles. Researchers reported no significant differences between lens types in head movements, reaction times, catching performance, speed changes, or steering.
Similar Visual Experiences
Two additional analyses used data from SightGlass Vision’s CATHAY clinical study of children ages 6 to 13. In one analysis, researchers found visual disturbances, including glare, halos, and hazy vision, were infrequent with both DOT and single-vision lenses. When reported, the visual disturbances were predominantly mild and minimally bothersome.
The other analysis examined children’s perceptions after two years of wear, including distance, near and night vision, visual acceptance, satisfaction, and overall impression. More than 91% of responses across the six measures were positive or neutral, with no significant differences between lens groups.
“What we’re seeing with DOT lenses is remarkably consistent behavior across a range of activities,” says David Webley, senior director, clinical, medical and professional affairs at SightGlass Vision. “Children are not changing their gaze or head position to compensate for the treatment zone, and their performance during dynamic tasks is comparable to standard single vision lenses.”
