Sunglasses that protect against UV light are essential for astronauts and protect against visible light, which can also damage the eye. Astronauts should never look directly at the Sun as this may result in permanent damage to the vision-sensitive area in the eye, the retina. In space there is no atmosphere to help protect us from some of the damaging effects of the Sun's energy. When astronauts spacewalk, however, they put on reflective visors to protect the eyes when they are working in direct sunlight.
