Its lightweight clip-on design fits over most eyeglasses and includes a flip-up lens plate for convenience. Ideal for precision tasks like jewelry-making, watch repair, and detailed inspections, it comes in multiple colors and includes a protective case with a one-year warranty. ## Description 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 ## Features - Eyeglass clip-on binocular visor with 1.75X magnifying lens plate for hands-free viewing - Ground and polished glass prismatic lens for improved focus and reduced eye strain - Clips on to eyeglasses or to included eyeglass frame - Lens plate tilts out of way when not needed - 14" focal length for a variety of uses ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000EMDFNS | | Are Batteries Required | No | | Brand Name | Donegan Optical | | Global Trade Identification Number | 00633096000847 | | Item Weight | 0.25 Pounds | | Lens Material | Glass | | Magnification Strength | 2.5 x | | Manufacturer | Donegan Optical | | Manufacturer Part Number | CO-3 | | Model Number | CO-3 | | Number of Items | 1 | | UPC | 098678229175 633096000847 | | Unit Count | 1 Count | ## Product Details - **Batteries required?:** No - **Brand:** Donegan Optical - **Item weight:** 0.25 Pounds - **Lens material:** Glass - **Magnification strength:** 2.5 x ## Images ![CO-3 Clip-On Binocular Magnifier, 1.75X Magnification, 36cm Focal Length - Image 1](https://m.media-amazon.com/images/I/71N1P9W7spL.jpg) ## Available Options This product comes in different **Size Name** options. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/258339348-co-3-clip-on-binocular-magnifier-1-75x-magnification-36cm](https://www.desertcart.hk/products/258339348-co-3-clip-on-binocular-magnifier-1-75x-magnification-36cm) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-10-30*
