Elgin, Illinois | September 2026 โ Good-Lite Company, a leading provider of vision testing and diagnostic products, is pleased to announce an exclusive U.S. partnership with Frisby Stereotest, bringing the internationally recognized glasses-free stereo vision test to clinicians, researchers, and educators across the United States.
Through this new partnership, Good-Lite will serve as the exclusive U.S. distributor of Frisby Stereotests. The agreement combines Frisby's established approach to stereoacuity testing with Good-Lite's domestic assembly, distribution, and customer support in Elgin, Illinois.
For more than 50 years, Frisby Stereotests have been used by eye care professionals around the world to assess stereopsis and depth perception in both children and adults. Unlike many traditional stereo vision tests, the Frisby Stereotest uses real depth rather than special viewing glasses, providing clinicians with a simple, intuitive method of evaluating stereoacuity.
Under the partnership, component parts will be supplied directly by Frisby, with final assembly and distribution taking place at Good-Lite's facility in Elgin, Illinois. This collaborative approach allows Good-Lite to offer the Frisby Stereotest to the U.S. market at a more competitive price while providing customers with domestic inventory, fulfillment, and support.
โFrisby is a natural addition to the Good-Lite portfolio,โ said Donovan Livingston, Business Development Specialist at Good-Lite. โIt has a long clinical history, it is easy to administer, and its glasses-free design offers something genuinely different within our stereo vision lineup. We are especially excited about the opportunities we see in clinical practice, optometric education, and clinical research.โ
Good-Lite plans to introduce Frisby Stereotests to colleges of optometry and other clinical education programs throughout the United States. The company also sees significant potential within the clinical research and contract research organization (CRO) markets, where standardized, easy-to-administer vision assessments can play an important role in multicenter studies and clinical trials.
The partnership brings together two organizations with longstanding histories in vision assessment. Good-Lite has been developing and supplying vision testing products since 1923, while Frisby Stereotests have been used internationally for more than five decades.
Good-Lite will support the U.S. launch through educational outreach, digital marketing, clinical research initiatives, and its established network of eye care professionals, educators, researchers, and distributors. Eye care professionals can also learn more about theย Frisby Stereotest range and testing options.
