โ ๏ธ Why Standard Single-Vision Lenses Are Not Enough
Single-vision (SV) spectacles correct your child's vision clearly at the centre, but they create hyperopic (long-sighted) blur in the peripheral retina. Research has shown this peripheral hyperopic defocus is a signal that tells the eye to keep growing longer โ making myopia worse over time. SV lenses correct the symptom but do not address the underlying progression.
Children wearing SV lenses in clinical trials consistently showed faster progression compared to those wearing myopia management lenses (0.44โ0.80D more progression per year).

๐ซStandard Single-Vision LensesNOT RECOMMENDED
Corrects central vision only โ causes peripheral hyperopic defocus
SV lenses are the control group in every clinical trial. They do not slow progression and may contribute to it through peripheral hyperopic defocus (Berntsen et al., IOVS 2013; Smith III et al., IOVS 2005).
