We weren't kidding about the ophthalmoscope! Here is an early version of OmniMask tested by a medical doctor wearing an ophthalmoscope.
At the time the OmniMask filter housings and also the headgear were still in development. In fact, if you look closely you might spot that we borrowed and adapted CPAP headgear for this test!
Besides additional proof of our great eyewear support—and a bit of history about OmniMask development—we include this photo to make the point that early and frequent testing of core features with real users is one of the best ways we know to build better products.
