SightGlass Vision DOT

The SightGlass Vision DOT 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 lens incorporates 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.
