for instance can cheap reading glasses harm eyes

my other half is a nurse and only uses non prescription glasses. they're not harmful but I always believe in getting prescription glasses that suit you specific needs. As a nurse, she wouldn't wear them if they were harmful, but I don't think they're as strong as she really needs.

Non Prescription Reading Glasses

Not really, but you should have your eyes checked by an optometrist or an ophthamologist to ensure that you are wearing the correct prescription. If you buy glasses to read and you get the incorrect prescription, you can cause yourself to become dependant on them constantly. The best advice would be to see a doctor and get your prescription and then if you want to buy the cheap glasses, at least you will have the correct prescription!

I learned my lesson the hard way. I had 20/20 visiion but needed glasses for reading as I got older. Non prescription glasses are very cheap, so that's what I went for. Then I had problems (no eye test for 2 years) and found to my horror that I not only had raised eye pressures but also, as it turned out, macular degeneration. Get your eyes tested every year, you can still use the prescription to ensure you get the right non prescription glasses.

Hi there R C (Is that you Ryan?)
Non prescription glasses, or as you say, 'cheap' glasses will not harm your eyes, but they are only devised as a basic aid to help you see a little better. Prescription glasses are made up specifically for your eyes only...(was that a james bond film lol), and they are a much better aid to your eyes than non prescription.

Prescription glasses are specifically made for you by your optician, non-prescription glasses can be picked up at places like Boots, all you do in that case is, try different pairs on until you can read a chart, very inaccurate though.

The main difference betweem OTC readers and Rx readers is that OTC are mass produced and proper measurements have not been taken for pupillary distances. Also, OTC readers (otc=over the counter) do not have any astigmatic correction, if you have an astigmatism.
Another thing that most people don't realize is that when you purchase otc readers, most likely you will be buying them too strong or too weak.
A prescription reader is made using your sphere powers and adding that to the bifocal power prescribed.
Let's say your Rx for the right eye is: +1.50 -.50 x65 add +2.00.
Add your sphere power to the add power and your true reading power would be +3.50 -.50 x65. You would do the same for the left eye.
Hope that explains.

yes prescription glasses are exspcialy suited to your eyes so that your sight is the best it can be
non prescription glasses are built for someone else or just average lenses which means it could make your sight worse in the long run

Cheap reading glasses are not recomended, because they're not made specifically for you and your exact prescription, and if you have an astigmatism or prism, there's no correction in those glasses for that.

Yes,non prescription you can buy just about anywhere these days..You just look through and when you find a pair that suits your reading requirements,you buy..Prescription ones are bought through a qualified optician who tests your eyesight and decides what is right for you...
