I'm sure many of you have seen this image floating around online at some point.
It seems a rather neat idea, though I'd be worried about any sort of accident, or even potential fight, ripping that piercing right out.
But, what if the lenses attached with magnets instead?...
Be careful with hanging stuff from your magnet implant: the pressure on your skin isn't necessarily great but it's constant and unrelenting, and you could cause necrosis of your skin the magnet pinches in as little as one hour. That's mostly the reason why I never pursued magnet implants to attach things to my body (and also because I want to retain the ability to get an MRI done)
