GREEN ISLAND, N.Y.--Astronauts on the current Discovery mission are wearing Silhouette frames. The company’s Titan Minimal Art frames carry NASA’s Certified Space Technology distinction and have been the exclusive eyewear for astronauts for the last several years.

The extremely light weight of the frames, 1.8 grams or 10 grams including the lenses, minimizes pressure on the face.

Special sunwear lenses were developed as the only concession to adjust to the extraordinary conditions in outer space. The specially developed sun lenses are much darker and coated with an ultra-thin gold layer for better protection against the intense light rays encountered in space.
