Re: Off the peg reading glasses
Hi, I think you owe it to yourself to get proper prescription eyeglasses.
Here in Australia, the eye test is fully rebated by Medicare, and the optician is obligated to return the prescription to you if you request it. That's the law. You can ask for the prescription and walk out of the shop. They don't like it but have to do it. Then, on the internet it's relatively easy to get a cheap pair of prescription glasses. I buy mine from the US and they cost as low as $10US including nice frames. I sometimes pay a few dollars more and get a scratch-resistant anti-glare coating.
The ones you talk about cost almost nothing to produce and basically suit long-sighted ppl who have trouble reading - this is the natural progression for many.
So there is an adjustment to long-sightedness and another for magnification - this because most ppl see better when things are magnified. In summary there is a rough correction for being long-sighted (sphere), no correction for astigmatism (cylinder or axis), and no eye-to-eye corrections. Money wasted.
