Now you can finally read the fine print!If you are farsighted or have reading glasses then this app is perfect for you.To use EyeRead choose between 2x, 3x or 4x magnification and hold the iPhone camera 4-5 inches (5-8 centimeters) away from the item you want to see magnified. Your item should be well lit for the camera to display it properly. The app makes use of the autofocusing feature of the camera and in poor light conditions this wont work as well.NOTE: EyeRead uses the iPhone 3GS autofocusing camera so it will only work on iPhone 3GS. Eye Read is also compatible with iPhone 4 camera.
