SOUTHAMPTON — SightGlass Vision announced that its Diffusion Optics Technology (DOT) spectacles for myopia control are now available for early access in the United Kingdom. Designed to utilize contrast management, these lenses provide an effective way for clinicians and families to help fight the growing epidemic of childhood myopia.
In the U.K., the prevalence of myopia in children has more than doubled over the past 50 years, with onset starting at a younger age, increasing their likelihood of higher myopia later in life.1,2 Every diopter of myopia progression increases the risk of serious eye conditions, but every diopter saved can reduce future eye health risk by up to 40%.3
“Introducing DOT lenses in a new country is always an exciting moment for us because it means we can offer even more eye care professionals this globally trusted tool to protect their young patients’ vision,” said Andrew Sedgwick, CEO of SightGlass Vision. “With over one million children already having worn DOT lenses,* we look forward to working with the U.K. optical community to expand access, intervene early, and help preserve children’s eye health with this highly effective technology.”
Clinical studies have demonstrated DOT lenses’ efficacy and comfort: they can slow average myopia progression by up to 75% after 12 months of wear across diverse populations, and 93% of children said they love their glasses with DOT™ lenses.4-7‡
Tools for ECPs
SightGlass Vision will be hosting a webinar on 15 October, “Manage Contrast to Manage Myopia: Introducing DOT Lenses,” where U.K. eye care professionals can learn more about the unique lens design, the supporting clinical research, and ask questions to senior members of the SightGlass Vision team during a live Q&A. Registration for the webinar is now open here.
