All I know is that I needed glasses for a while now.
If you can't go to the eye doctor, go on ebay and get a pair of +1 diopter and a pair of -1 then see which one helps. Buy 1.5s next and keep going if you need to.
About $15 each from China if you need negative diopters for distance, reading glasses (+ diopters) are much more common and cheaper.

“No political truth is of greater intrinsic value, or is stamped with the authority of more enlightened patrons of liberty: The accumulation of all powers, legislative, executive, and judiciary, in the same hands .… may justly be pronounced the very definition of tyranny.” —James Madison, Federalist 47
“All the powers of government, legislative, executive, and judiciary, result to the legislative body. The concentrating of these in the same hands, is precisely the definition of despotic government. An ELECTIVE DESPOTISM was not the government we fought for; but one .... in which the powers of government should be so divided and balanced among several bodies of magistracy, as that no one could transcend their legal limits, without being effectually checked and restrained by the others.” — Thomas Jefferson, commentary on Federalist 48
