Although good eyesight might be a worthy tradeoff for astronauts, considering that they get to see things that very few people will ever set their eyes on, NASA has decided to help them with the Superfocus glasses. These spectacles boast an adjustable inner lens that holds optical fluid to provide better focus for near- to middle-distance vision.
According to Ubergizmo, the average age of an astronaut is 48, by which time many of them might be suffering from a condition known as presbyopia, in which the lenses of a person’s eye become inflexible, making it tough to focus on close-up objects. The Superfocus glasses would rectify the matter.
The Superfocus glasses may look rather geeky, but they do the job, that's for sure.
