Sight Sciences, Inc. (the “Company”) was incorporated in the State of Delaware in 2010 and is headquartered in Menlo Park, California. The Company is an ophthalmic medical device company focused on the development and commercialization of surgical and nonsurgical technologies for the treatment of prevalent eye diseases. The Company’s mission is to develop transformative, interventional technologies that allow eyecare providers to procedurally elevate the standards of care — empowering people to keep seeing.

The Company's product portfolio aligns with its two reportable operating segments: Interventional Glaucoma and Interventional Dry Eye. The products for the Interventional Glaucoma segment consist of the OMNI® Surgical System family of products ("OMNI") and the SION® Surgical Instrument ("SION").
