Best Buy Donegan CO-5 Clip-On Binocular Headband Magnifier, 2.5x Magnification, 5 Diopers, 8" Focal Length Reviews

• Binocular magnifier can be used with included frame, or clipped onto prescription eyeglasses to provide hands-free magnification and viewing for a variety of applications, such as jewelry-making, watch-making, needlework, artwork, fly-tying, electronic inspection, book-reading, print inspection, and stamp-collecting
• Available in multiple dioptric strengths that provide a specific magnification power (X), depending on the distance from the object (focal length)
• 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 2.5X magnification (at a distance of 8")
• Dual acrylic lens system has optical-grade lenses ground and polished into prismatic lenses for quality, clarity, and durability
• Can be used with included frames, or clipped onto prescription eyeglasses

Donegan CO-5 Clip-On Binocular Headband Magnifier, 2.5x Magnification, 5 Diopers, 8" Focal Length

The Donegan clip-on, binocular, hands-free magnifier with frame has a dual acrylic lens system with optical-grade lenses ground and polished into prismatic lenses, and is available in multiple colors, and multiple dioptric strengths (indicated by the number in the model) which provide specific magnification power (X) at a specified distance from object. This magnifier enhances the size and resolution of an object or image, and is commonly used for a variety of applications such as jewelry-making, watch-making, needlework, artwork, electronic inspection, fly-tying, book-reading, print inspection, and stamp-collecting.

The clip-on, binocular, lightweight (0.417 lbs) magnifier features binocular lenses that come with a frame and clip that attaches to the frame or eyeglasses. The magnifier can be worn over prescription or safety eyeglasses, and has the ability to flip up when not in use. Spring-loaded pivot screws hold the headband in a raised or a forward-facing position. The magnifier is available in assorted colors such as black, and blue. It comes housed in a protective shell and carrying case. It has a one-year limited warranty. 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 2.5X 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,
