Reveal is designed to fit most adults and has been tested on a wide variety of face shapes and sizes. The Medium size will fit most women, and the Large size will fit most men.
However, people with very small or large faces may not achieve a good fit with either a Medium or Large Reveal.
Refer to the illustrations on the opposite page to understand how your Reveal should fit to achieve a comfortable and secure seal.
Ideally, the top edge should rest just below the bridge of your nose, and the bottom edge should be just above the point of your chin.
Properly fitted, your Reveal is wearable with average-sized glasses and will not obscure your lips or mouth.
