Well, did you know that there's a relatively well-hidden feature in iOS that allows you to set the brightness of your iPhone/iPad even lower? We bet some of you didn't!
Of course, we will show you the ropes on how to enable this feature. In fact, Apple's iOS 8 has a majority of other accessibility features that aim to make life easier for those users who have certain types of visual impairment. Then again, some of these might turn out to be quite useful even for iOS users who have never cared what's inside the accessibility menu of their iDevices.
