If you are young, and by that I mean you are under 40, then it is fairly likely that at some point in your life, you will need glasses. You should be going to get your eyes tested every two years, and these tests will not only check to see if your eyesight requires some correction, but they also allow a skilled optician or optometrist to detect any underlying health conditions. Many illnesses can be detected by studying eye health, even if that condition is not a problem with your eyes!
Whereas it is important for people younger than 40, with sudden development of blurred vision or headaches, to see an expert, for those of you over 40, there is an inevitability that your eyesight will start to deteriorate relentlessly from now on. This is all a part of the normal aging process and is a condition called presbyopia. Youngsters usually wear prescription glasses for myopia (or shortsightedness); for middle aged people, the opposite normally happens, and reading glasses are required.
The great thing about presbyopia correction is that non prescription glasses are readily and cheaply available in many retail outlets, especially at some of the large pharmacies or drugstores. It still makes sense to go and get your eyes checked over by a specialist, to check for more serious conditions; but you can decline to buy the reading glasses from the expensive optician’s store, and go somewhere cheaper instead.
In most places that offer non prescription glasses, you get to try on varying strengths of lens, and then attempt to read a passage of text off a card. You keep trying different strengths until you find one that allows you to read the text perfectly. Then you simply choose a style from the selection available for that particular strength, and that’s it! Perfectly good cheap reading glasses without the need for an expensive prescription.
