Children wearing SightGlass Vision Diffusion Optics Technology lenses had no increase in astigmatism compared with children wearing control lenses, according to studies presented at the Netherlands Contact Lens Congress.
The study was conducted after other research suggested that astigmatism could increase with the use of peripheral defocus, the myopia control method used by MyoVision (Zeiss) and Essilor Stellest (EssilorLuxottica). SightGlass Diffusion Optics Technology (DOT) lenses work through a different mechanism: contrast modulation.
