Being an Astronaut is Bad for your Eyes

Now this story was picked up worldwide by all sorts of newspapers - I just happened to read it on 'The Australian' site.  Which begs the question: to whom exactly is this an important issue?  Of the (roughly) 7,000,000,000 people wandering around the planet, there are possibly 25 of them who may be directly affected by these findings.  Are you liable to be blasting out of the clammy embrace of the earth's orbit anytime soon?  And if so, are you planning on being  gone for long?  If the answer to both of these questions is 'yes', then you may wish to schedule a visit to Vision Express on your return, as you may (possibly) have damaged your eyes a little bit.  


Everyone else can relax.
