Reader eyeglasses, reading glasses and simply readers actually refer to the same product. They are regular eyeglasses for presbyopia correction. Name variations are not the key point. The key point lies in the help they can offer. And before discussing in depth the functionality of reading glasses, it is necessary to detail the reason, symptoms and signs of presbyopia that is the source causing the use of reading eyewear. This condition usually occurs at about 40 and will bother a vast majority of people over this age. Most people can not escape this eyesight problem because they are caused by the eye’s natural aging process, an irreversible process. In some cases, presbyopia is called an age-related condition and differs from these eye refractive errors including astigmatism, myopia and hyperopia. These refractive errors are linked with generic and environmental factors which lead to irregularly shaped eyeballs. Exactly, presbyopia stem from a gradual thickening and loss of flexibility of the eye’s natural lens.
It is usually a necessity for presbyopic patients to ask reader eyeglasses for help because there are consequently bothersome symptoms. One phenomenon that can be found among presbyopic patients is that they usually hold books, magazines and even menus at arm’s length, in which distance they can focus properly. Otherwise, everything close-up is blurry. And some serious conditions like headaches, eye strain and fatigue may follow. Using a pair of reading glasses can help prevent nearly all these symptoms. With readers on the face, it is no longer needed to hold reading materials as far as possible intentionally.
Today, there are custom-made and pre-made reading glasses, both of which are widely used. Some brands even offer multifocal reading glasses that can deal with other vision problems at the same time. These glasses take a same principle in correcting presbyopia. As the target buyers of reader eyeglasses, patients who develop presbyopia may find it is helpful to know that there are still some other solutions to this condition. Contacts lenses in multifocal form are also widely used for presbyopic correction. And for a relatively permanent treatment, it is possible to replace the aging lenses with artificial multifocal lenses through an eye surgery.
