SightGlass Vision, Inc., a medical device company developing spectacle lenses to slow the progression of nearsightedness or myopia in children, today announced its ground-breaking, pivotal clinical trial to control nearsightedness in children, CYPRESS, is currently enrolling patients in the U.S. and Canada. The CYPRESS study is evaluating the safety and efficacy of the company’s novel lenses compared to standard spectacles to reduce the rate of progression of myopia in children aged six-to-nine years old. Glasses and contact lenses currently available in the U.S. only correct myopia, but do not help prevent it from getting worse.
