Is there a difference in reading glasses versus computer glasses?

[Paincourtville]

I have some reading glasses and I want to use them to see on the computer.I am not sure if the reading glasses can be used for computer. When I wear my reading glasses for seeing on the computer, I usually get headaches.Why?

In fact,reading glasses are different from computer glasses.They have different purposes.reading glasses focus on the distance that from your eyes to a book,that is , a arm length.However,computer glasses focus on the distance from your eyes to the computer screen, which is usually farther than the distance for reading glasses.

Yes.They are different.They are used for different distance, so you'd better not use the reading glasses for computer.Otherwise you will get headache and it may damage your vision.

Reading glasses are suitable for reading distance (30mm)while computer glasses are for computer distance(60mm). You'd better wear special made computer glasses when you using computer.
