A maker of medical devices for the eyes, Sight Sciences builds tools that treat glaucoma and dry eye disease. Its OMNI Surgical System is a minimally invasive device that lowers eye pressure without leaving an implant behind, while its TearCare System warms and clears blocked eyelid glands to relieve dry eyes. Founded in 2011 by brothers Paul and David Badawi in Menlo Park, California, the company set out to offer "interventional" alternatives to the traditional eye-drop-first approach. The name OMNI comes from the Latin for "all," reflecting that the device addresses all three known points of resistance in the eye's fluid-drainage system.
