Focusable glasses provide magnification for easy viewing of up-close reading tasks
Two lenses focus separately to adapt to most magnification needs
A dioptric number and a magnification number are not the same thing. Diopter strength represents a specific magnification power (X). For example, a 5-diopter provides 2 X magnification (at a distance of 8″)

Eschenbach MXDT-16245-01 focusable glasses have two plastic, 32 mm diameter lenses with + or – 3D and 2.1X magnification. The glasses ease up-close reading, and the lenses can focus separately to adapt to most wearers’ magnification needs. An open-saddle bridge distributes the frame’s weight for a comfortable fit. The glasses are often used to read print on a computer screen, a book, or a prescription label.

The Eschenbach MXDT-16245-01 frames measure 137 mm (temple-to-temple width) with 135 mm temple length, and weigh 49 g (1.7 oz.). The glasses accommodate a 60-68 mm pupillary distance (PD) range. The magnifier has a nylon zippered cased and a three-year warranty.

A dioptric number and a magnification number are not the same thing. Diopter strength represents a specific magnification power (X). For example, a 5-diopter provides 2 X magnification (at a distance of 8”). Diopter (D) is a technical term for the measurement of the light curvature and thickness of a lens. A dioptric number and a magnification number are not the same thing. Diopter strength represents a specific magnification power (X). For example, a 5-diopter provides 2 X magnification (at a distance of 8”). The higher the diopter, the more magnification a lens can provide. As magnification increases, distance to the object (focal length), and field of view (diameter, or narrowness of view) decrease.Magnifiers and prescription eyeglasses have a diopter value, such as 1.5 or 2. The dioptric strength of an accessory lens, such as prescription eyeglasses or an eye loupe, must be added to the dioptric strength of the magnifier to calculate total magnification.

Magnifiers are devices used to enlarge the visual appearance of an object or image. Magnifiers come in a variety of styles such as hand-held, headband, standing, clip-on, eye loupe, and those that hang in a necklace form, or fit in a trouser pocket. Magnifiers are commonly made of plastic or glass. They can have one or more lenses with varying magnification abilities, and can have a binocular configuration with a single lens, or two separate lenses. They are sometimes used with LED or fluorescent light sources to help control viewing capabilities. Magnifier ability is often expressed as magnification at a specific length. For example, 1.75X at 14” means that when a magnifier is held at 14” from a viewer’s eyes, the object will be magnified 1.75 times (X) its actual size. As magnification increases, viewing areas and focal length decrease. Magnifiers sometimes have a diopter number, expressed as + or – D, which is a measurement of strength (or power) of the lens. Some magnifiers are marked with a dioptric number on the lens. A high diopter number has a higher magnification than a low diopter number. Aspheric magnifiers, unlike spheric magnifiers, produce a sharp image to the edge of the lens for less distortion. Magnifiers are widely used in jewelry inspection and fabrication, watch-making, needlework, artwork, fly-tying, electrical inspection, reading, print inspection, and stamp-collecting.

Eschenbach Optik of America manufactures low vision aids and magnification devices such as magnifiers, glasses, and telescopes for inspection, quality control (QC), and scientific applications. The company is headquartered in Danbury, CT.
