I couldnt get my head and bifocals at the right angle the other day to read the serial number in a wash machine. I searched the app store and found this Glasses app. The only thing that distinguished it from half a hundred similar apps was the 5 star rating, so I installed it. It may be one of the most useful apps I have on my iPhone! Remember the old days when you had to input a 700 digit number off the back of the CD case to install Windows? If youre ever looking for a really good macro camera, the one built into this app is absolutely fantastic! Well done, Yodel!
