When you reach the point when it becomes difficult for you to read up close without stretching your arms to the limit, it might be the time for you to consider single-vision reading glasses. Reading glasses are prescription glasses which generally come in two main styles: one is the full frames, which comes with the entire lens being made to the reading prescription, and half-eyes, that sit down on the nose.
Full reading glasses are the most suitable prescription glasses for people who spend a lot of time concentrating on material close-up. In case you look up across the room through these prescription glasses, everything appears blurred.
On the other hand, half – eye reading glasses allow one to look down and through the lenses for near work, and if you have to see in the distance, you can look over these prescription glasses.
Another kind of prescription glasses called tinted reading glasses comes with UV protection. There is also the sunglass bifocal, with a non-prescription upper half for looking far away and a reading prescription in the lower half for close – up.
Ready-made reading glasses can be purchased from pharmacy or optical stores specializing in prescription glasses or even a department store. These glasses are inexpensive and come in varying shapes and designs. But a major drawback of ready-made prescription glasses is that same in both lenses, and the location of the optical center of the lenses is not customized for each wearer. Most people do not have the same in both eyes, and almost everyone has at least a small amount of astigmatism correction in their prescriptions.
Now-a-days, it is easier to purchase custom-made prescription reading glasses. You can browse through various online stores dedicated to glasses, where you can put in your prescription and get your glasses customized. These glasses are offered at discounted rates and the style and range are even more eclectic than the ones found at any high street optical store.
