20D Lens Flange

Lens flange for an ophthalmology/optometry 20D condensing lens. Inspired by the Volk ClearPod. Prevents glass fogging from patient masks. Lens snaps into place from behind. Top gaps allows flange to bend. Smoothed edges and corners for safety. May be resized for 78/90D lenses. Note: NOT a universal fit - modify dimensions as needed for each unique lens model.
