Do you wear glasses? Yeah, me too. See if you can resist this, then: new eyeglasses that allow you to adjust prescription yourself. From phys.org:
A new kind of eyeglasses is now available from a British company that allows the wearer to adjust the prescription anytime, anywhere, via small thumb-dials on the sides. Called, Eyejusters, the glasses make use of a technology called a Slidelens, which very aptly describes how these glasses do their magic. Each lens is actually two lenses that have slightly different shapes; turning the thumb-dial causes one lens to move slightly left or right and that changes the focal point for the wearer. The lenses are moved until the person doing the focusing finds the sweet spot; which is exactly how users focus a pair of binoculars. [continue]
Isn’t that just too cool for words? I image companies that make reading glasses — especially the kind you see for sale in supermarkets and drug stores — will be less than pleased about this, though.
