According to Ubergizmo, NASA supplied the astronauts on the recently launched Discovery with special glasses that would make it easier for them to see in space.

Superfocus glasses aim to help folks suffering from presbyopia. The glasses act like a regular pair of spectacles, with prescription lenses on the outer layer, while a pair of inner lenses helps wearers focus on different distances. The inner lenses contain a clear optical fluid that can be adjusted by using the slider on the bridge of the glasses.
