Clinical Report: Control the Contrast Debuts Globally

Overview

SightGlass Vision has launched the 'Control the Contrast' campaign to enhance awareness of contrast management in myopia control. The initiative promotes the use of Diffusion Optics Technology (DOT™) spectacle lenses, which have demonstrated a significant reduction in myopia progression in children.

Background

The rising prevalence of childhood myopia is a growing concern, particularly due to increased indoor activities that create visually uniform environments. These conditions may contribute to abnormal eye growth, making effective management strategies essential. The introduction of DOT lenses represents a novel approach to mitigating myopia progression through contrast modulation.

Data Highlights

Clinical data indicate that DOT lenses can slow average myopia progression by up to 75% over 12 months in children.

Key Findings

• DOT lenses have been fitted to over 1.5 million children across various countries.
• The CYPRESS trial showed less axial elongation in children wearing DOT lenses compared to single-vision controls (0.59 mm vs 0.72 mm).
• Children using DOT lenses experienced a smaller myopic shift in cycloplegic spherical equivalent refraction (−0.83 D vs −1.16 D).
• 43% of DOT wearers were refractively stable at 36 months, compared to 19% in the control group.
• The campaign aims to encourage earlier intervention by increasing clinician awareness of treatment options.

Clinical Implications

Eye care professionals should consider integrating DOT lenses into their practice as a viable option for managing pediatric myopia. Increased awareness and understanding of contrast management can lead to earlier interventions, potentially improving long-term visual outcomes for children.

Conclusion

The 'Control the Contrast' campaign represents a significant step in addressing childhood myopia through innovative lens technology. By promoting contrast management, the initiative aims to enhance clinical practices and improve patient care.
