Our beloved fatherteacher Ben Popken seems just fine with his newly lasered eyes, but not everyone sees such great results, says Reuters: “Blurred vision, dry eyes, glare and double-vision have led to depression and in some cases suicide, several patients told a U.S. Food and Drug Administration advisory panel.” These patients want the FDA to take a more active role in regulating the LASIK industry (currently the FDA regulates the equipment but not the people who use it).
The FDA has a set of specifications on proper eye care, and apparently people who buy their contact lenses online are less likely to follow those rules, reports a new study. The gap comes from having less trained, in-person medical attention and up-to-date prescriptions, and not poorer cleaning habits (although we wouldn’t recommend using dollar store saline solution just to save a few bucks).
If you force a test subject to wear mirrored sunglasses that reverse the polarity of their vision, making it seems as if they are wandering around in an upside-down world, their vision will turn right-side up again in a few days. It seems the brain automatically orientates itself to a ‘proper’ top-down orientation; we’re psychologically asymmetrical.
