Factors of AMD magnifiers

People with age related macular degeneration often resort to some types of magnifiers for help. Nowadays, AMD magnifiers come in various types that AMD patients need to consider several factors whilst choosing them. Depending on different tasks, styles of AMD magnifiers include reading magnifiers, lighted magnifiers, computer screen magnifiers, dome magnifiers and so on.

The first factor is the lens size. In general, a lens should be large enough for AMD patients to perceive a wide range. On the other hand, the lens should be small enough to be carried in a pocket or purse. A second consideration can be given to magnification, which represents the ratio between the apparent size and the true size of the object being perceived. For instance, a 10X lens enables an object to appear ten times larger than its actual size.

Focal length is another aspect to evaluate while purchasing AMD magnifiers. This measurement is the distance between the magnifier and the patient’s eyes. In addition, this phrase can also be used to describe the distance between the magnifier and the target object. In a normal case, a shorter distance between the magnifier and the object provides a stronger magnification.

Like eyeglasses, AMD magnifiers’ lenses can be made of different materials. Glass lenses usually allow more light to be transmitted through the lens and offer clear optical qualities. Furthermore, glass lenses are hard to be scratched. Compared to glass lenses, acrylic lenses are more lightweight. They are shatter-resistant and scratch-resistant. In fact, acrylic lenses have been the majority in the realm of AMD magnifiers. They can offer exceptional optical quality.
