Do you find it more difficult to read Neatorama as you get older? Astronauts age too (their average age is 48) and they may experience a condition called presbyopia that makes it more difficult to focus on close objects. These Superfocus specs provided by NASA have an inner lens containing clear optical fluid that adjusts the focus by moving a slider on the nose bridge.
It shouldn't be too difficult to add a distance sensor and an actuator to make them auto adjust. My problem with bifocals is that I often need to see something up close which is high in my visual field.
Imagine a African government that actually cared about it's citizens instead of lining their own pockets to actually give them anything except war, rape, disease, starvation, corruption, and despair.
Looks like another one of those "innovations" that isn't as good as boring old technology.
Nope, can't imagine that happening anytime soon.
