Bifocal reading glasses

devices include low vision glasses, but there is a much weaker, which is now available that can help patients live with symptoms of macular degeneration. While laser surgery is the "wet" variety of age-related macular degeneration or AMD, there is no known cure for "dry" form of the leading causes of blindness. However, the low vision devices is like a sacrifice to help the best of what is before his eyes.
Age-related macular degeneration (AMD), affects the central part of the retina, and thus to determine the ability of small details, such as print and facial images. Basically, it develops a "hole" in a vision in which the subject is to find an object to find youngest of this "hole", the object can be seen clearly. Therefore, the goal of low vision devices to the apparent size of these objects must be increased.
Because we use our eyes to different ways in different situations, there is no single solution to treat the symptoms of macular degeneration. A patient may need different products with low vision. Bifocals are one of the most famous and vision devices most commonly low, but it is not appropriate for all the symptoms of macular degeneration. Bioptic glasses for the blind who are also known as Bioptic telescopes, low vision devices, which are actually miniature telescopes mounted on a pair of normal glasses. This low vision devices can be adapted to the needs of a wide range of activities, both distance and near vision. While glasses Bioptic for the blind to work the same way (tilts his head slightly forward), they differ from bifocals, the telescopic lens is not designed into the primary objective in itself.
Other products for visually impaired age-related macular degeneration with products such as portable digital magnifier that is similar to reality virtual glasses, and is used in combination with a pair of special glasses. One of the most interesting of the low vision market consists of a miniature television camera that is actually based on the surface, which increases the reading of the patient, and send the electronic images projected the image on the inner surface of the glasses! This system allows the patient's head to remain upright, there is no need to tilt the head.
Obviously, this high-tech visual aids are very expensive in the present. If, however, is the history of other technologies such as computers and DVD is a flag that was to come, the cost of such a device for the visually impaired are essentially in the coming years.
