Description of Business

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: Surgical Glaucoma and Dry Eye. The products for the Surgical Glaucoma segment include the OMNI® Surgical System ("OMNI"), which is an implant-free, handheld, single-use, therapeutic technology that enables ophthalmic surgeons to perform a comprehensive procedure (i) indicated in the United States to reduce intraocular pressure in adult patients with primary open-angle glaucoma, and (ii) CE Marked for the catheterization and transluminal viscodilation of Schlemm’s canal and cutting of the trabecular meshwork to reduce intraocular pressure in adult patients with open-angle glaucoma; and the SION® Surgical Instrument ("SION"), a bladeless, manually operated device used in ophthalmic surgical procedures to excise trabecular meshwork.
