Do I need glasses for +0.5 in both eyes?

I am 22 years old and said i have chronic headaches however i am seeing a neurologist and he claims its tension headaches he said for sure that is what is causing it and he said its impossible that small of a glasses prescription would cause headaches or for me to even notice at my age. The optemetrist wants to wear glasses FULL TIME and while im driving. I told him i feel sick wearing them from far and things seem disorted.. he said keep wearing them i will get used to them. My neurologist thinks its silly for such a small power.
