Before we are filling a prescription for the near-sighted, we must have a visual test. But many aged people who are purchasing reading glasses ignore this issue. They just buy them with the help of sense. We are accessible to reading glasses mainly in two ways, the custom-made and the ready-made. Reading glasses can be custom-made for each individual through an optical dispenser, or they can be purchased "ready-made" at a pharmacy or department store.
Ready-made reading glasses are available in lots of fun styles and colors so you can experiment with fashion, purchasing a somewhat outrageous pair of glasses without risking a lot of money. Ready-made reading glasses give the purchasers a great range to choose, colors, styles and prices. Although specialists recommend individuals who need to wear eyeglasses to have them custom-made according to their own needs, most of the patients prefer buying them at a pharmacy or department store. This type of eyeglass-shopping became very popular in the 1990s when it was estimated that over 30 million pairs were sold per year. One drawback to purchasing ready-made reading glasses is that they are essentially "one-size-fits-all" items. Headaches, eyestrain, and even nausea can result from wearing reading glasses that are too far off from your actual prescription.
Firstly, many cheap reading glasses are not made with optical glass, but industrial glass. It doesn't come out serious problem for a short time. With long time wearing, many side effects come consequently. Then, the refractions of two eyes may be different and the distance between eyes should be accurately tested. Finally, specialists suggest that medical optometry is necessary for the first time. It guarantees the accuracy of optometry and provides basic eye care. So when you are going to fill a prescription for reading glasses, go to see a optometrist first.
