This has been scientifically accomplished by using mirrors silvered on the front or firstsurface of the glass. To protect these sensitive mirrors from dust, objects and oxidizingagents, they have a dust-proof enclosure of clear non-refracting ophthalmic glass placed ina position where it cannot give any reflection of the radiograph to the observers eyes. The first surface reflection of the radiograph fogs and blurs the second surface reflec-tion of the radiograph from 5 to 15 per cent. Obviously the increased visual acuity of theradiograph equals the elimination of the fogging and blurring because of the increasedaccuracy in relief and detail in making deductions of position, shape, siz,e and pathology. The questions of those who have inspected or are using the Clear Vision StereoscopicBox ma
