Eyes are a difficult thing to replace. You can't exactly just stick a prosthetic in the socket and repair someone's vision; trust me, I've tried, it just doesn't work. The human eye is a complex organ, which makes replacement all the more difficult. Luckily, that challenge hasn't deterred scientists. In fact, the first bionic eye was just unveiled in the US - and believe me when I say, it's a sight for sore eyes everywhere. Japan Times Plus, it's quite the looker. Now, before you start throwing money at Sarif Industries Second Sight Medical Products, there are a few hitches. This particular bionic eye is designed for sufferers of a rare genetic disease, and it's still far weaker than natural eyesight. Not only that, this thing is slated to cost roughly $100,000 in Europe (the US price hasn't yet been confirmed) - the future, as it turns out, is very pricey at the moment. So yeah, you shouldn't be asking for this just yet - that comes later. Don't get discouraged just yet, though. This particular eye is surely a sign of things to come, and as the technology improves (and competition sprouts up), we should hopefully see the price drop as well. All in all, this is pretty cool. No, actually, it's better than cool - it's eye-ballin.
