                         Try out  glasses without buying them

Ditto.com is an amazing site where you can try out  glasses on your face without going out to shop.The process is very simple as well. All you need is a webcam and say a business card or anything of that sort.First the website will ask you to do is configure your webcam and ask you to move from left to right .Make sure that you speakers are on as you can hear instructions as to when to move and where and to stop.Then all you have to do is place the business card over your forehead without blocking your eyes or blinking and just like that you have your own ditto to try out hundreds of glasses and then go out later and get the cheapest looking alternative ;)
