If you need glasses you may not need to in the near future! (Kind Of) If you wear glasses you know about the time and hassle it usually takes to get your eyes tested every few years to see if you got to pay loads of money to get your glasses replaced if your eyesight has got worse.

Well, scientists from the University of Utah have created some prototype glasses which could make progressive lenses obsolete for the older folk. These glasses have electronically activated lenses which use infared to judge distance – then the glasses focus automatically and within 14 milliseconds, on whatever it is you’re looking at, regardless of distance. Once the glasses are ready for commercial use they could eliminate the use of multiple pairs for different uses for example instead of 1 for reading and 1 for driving,  you’d only require one pair of smart glasses.

To get the right setting for everyday use, the users upload their prescriptions to the glasses by pairing them with a smartphone over bluetooth. You still require to charge the glasses but, at least it saves you a lot money in the long run!
