Tunable glasses

Engadget reports via The Telegraph that a British inventor has designed a “tunable” eyeglass, one where the wearer can actually self adjust the lenses to suit their needs without needing a prescription. Apparently, the plastic lenses have sacs of liquid in the middle, with the wearer adjusting tha amount of the liquid using syringes. Once adjusted, the wearer removes the syringes and wears the glasses just like regular ones.

What’s great about this invention is that it’s aimed at third world countries where opticians may be scarce, expensive or both.

Personally, I’ve been wearing eyeglasses since my second year of highschool, and having to change prescriptions every so often is an expensive undertaking. I’d totally get me one of these if only to save time and money from going to the optician.
