Reading glasses and vision: perscription vs non-perscription

Vision is something that we should all take seriously, so never risk making eye problems worse by postponing a prescription. In some cases, however, prescription corrective lenses are not mandatory. Nowadays, glasses are available at drug stores or department stores for simply magnifying - without a prescription. Many vision problems require a corrective lens prescription, but if you just need a little magnification while reading, you might try some over-the-counter glasses. These glasses come in various strengths, which magnify 10, 20, 30 percent or more. These glasses also range in price from a couple of bucks to bigger money, depending upon what style you choose. The cheaper variety of non-prescription glasses may be easily scratched or give a distorted view of the world, so try them on for a few minutes before purchasing. Price should not be a factor, though, when debating on whether to get a prescription or buy over-the-counter glasses. Although prescription lenses are more expensive, if they are needed to correct a serious vision problem, it’s advised to wear the prescription, rather than purchase non-prescription glasses only to save money.

It’s difficult, if not impossible to tell the over-the-counter type of glasses from prescription glasses by glancing at them. Both the non-prescription and prescription glasses come in bifocals, sunglasses, and even designs that adjust according to brightness or darkness. Both also come in a variety of styles, colors and sizes to suit your needs. After using the non-prescription glasses for some time, you might realize that you need a stronger and more powerful lens as time progresses. If you find that you need a very strong lens, it might be time to have a vision test. Also, if your vision gets to the point where you have trouble seeing distances and close-up, it’s definitely time for an eye exam, since the non-prescription glasses are not available in a lens that allows correction for nearsightedness and farsightedness at the same time. In addition, non-prescription glasses do not assist in astigmatism problems.

For most vision problems, it’s best to see your optometrist on a regular basis and wear the recommended corrective lenses that are prescribed. Non-prescription glasses cannot take the place of prescription glasses for those who have serious vision problems. And, although wearing non-prescription glasses shouldn’t make your vision any worse, it might prevent you from seeing an eye doctor for a serious vision abnormality. If you’re going for a vision exam, ask your doctor if you would benefit from just buying a pair of magnifying glasses. Your doctor will know what’s best for you and he might agree that this type of lens is perfect for minor reading problems.

Untreated vision problems often cause headaches, blurry vision or other symptoms. If you notice that these problems persist after trying the non-prescription glasses, it’s good advice to have your eyes checked to see if you need corrective lenses. And, even though you wear a prescription for sight problems, that doesn’t mean that you can’t use the non-prescription glasses for reading purposes. The safest way to protect your vision is to have regular eye exams and talk to your optometrist before making eye glass decisions.
