How can you tell if you need reading glasses?

[Lakemoor]

If you get headaches or sore eyes while reading for more than a few minutes,or you couldd't thread a needle, or you always squint when you read magazines, books and Watch TV. At this time you need reading glasses.

When you can't see the small letters on your mobile phone or the news papers I think you need to use reading glasses.
