Why I feel painful while wearing my reading glasses?

[Layne]

Why do I feel painful when wearing my new glasses bought 2 weeks ago?

Go back to the place where you bought that pair and check if they did with the wrong prescription.

You feel pain possibly because you have a slight astigmatism which may cause pressing when you try to focus on the book.Don't hesitate to make an appointment for an examination to see your doctor to find out what the problem is. Otherwise the pain may get worse later .
