Myopia Profile

SightGlass Vision DOT Lens

The SightGlass Vision DOT 0.2 lens can be considered a first-line treatment for myopia in children, with one-year randomized controlled trial data published, showing robust myopia control efficacy. They are underpinned by a different mechanism and theory of myopia control than other designs - based on contrast theory rather than optical defocus theory. The DOT 0.2 lens incorporate incorporate Diffusion Optics Technology (DOT™): thousands of microscopic light scattering elements (microdots), each about one tenth of a millimetre wide. The microdots are not designed to produce peripheral defocus - they are designed to mimic more natural contrast while providing clinically equivalent visual experience to single vision lenses. DOT spectacle lenses manage contrast by softly scattering light before it hits the retina, and before the retina detects artificial contrast and signals the eye to elongate.

Diffusion Optics Technology (DOT) Spectacle Lenses
Spectacle lens for myopia correction and control, with Diffusion Optics Technology™ (DOT)
Central aperture (~5mm) to facilitate lens power measurement, surrounded by thousands of regularly shaped, irregularly spaced light scattering centers called microdots (each around 0.1mm ⌀), from edge to edge, that make up the treatment zone of the lens.
With full refraction, taking monocular pupillary distances and monocular fitting heights.

Diffusion Optics Technology - The Mechanism of Action

Diffusion Optics Technology™ is a new and unique lens technology designs to mimic more natural contrast to help slow down axial elongation to control and reduce myopia progression. Its unique Diffusion Optics Technology™️ is based on ground-breaking discoveries surrounding myopia progression. Spectacle lenses using its patent-protected approach incorporate thousands of light scattering elements called dots designed to mimic more natural contrast on the retina—a method intended to reduce myopia progression in children.
