An eyewear is always a liability, other than goggles that protect you from the sun, when youâre on the field (playing a sport). At the back of the mind, one is always conscious about losing them, in turn affection your concentration level. What if there were glasses that could fold into a cool watch? And when the game is over, you could it roll it back. Sadly, itâs just a concept and weâve reasons enough that promising concepts rarely make it real.
