The Receptor is an injection-molded fit-over frame that can be conveniently worn over prescription glasses, and provides excellent coverage from stray light through the top or side of the frame. Those with sensitive eyes or medical concerns for eye protection should use this frame for its superior coverage. A cloth case is included for safe storage.
The frame measurements are 62-14-150 (mm). To wear over prescription glasses, the total width of the glasses should be 135mm or less (5 3/8ths inches), and the height of the glasses 42mm or less (1 5/8th inches). To reduce internal reflections between the lenses, glasses that have an anti-reflection coating are recommended.
