How to read or Text at dark in an Android Smartphone or Tablet without ruining your eyes too much
Use the Screen Filter application which dulls the screen thereby reducing its brightness. I highly recommend not reading in darkness. But if you absolutely have to check mails or Reply to SMS near your bed and if you find the screen brightness too disturbing, try using this App "Screen Filter". Like I already said, don't read in the Dark! You are better off with that. Keep your eyes safe and Healthy!!! DO not use your phone in the dark.
