"Macular degeneration" will cause blurring in the center of the visual field. In severe cases, it will cause central visual field defects and gradually expand the scope of the defect. General spherical or aspheric lens magnifiers have the best imaging effect in the center of the mirror surface, but there are still deformation aberrations in the imaging around the lens, making it difficult to use for patients with macular degeneration. https://www.hwatang.com.tw/uploads/editor/Eschenbach/vtp762_0406-2-pl2.jpg Qiming series magnifying glass products adopt Aplanatic parfocal aspheric (aspherical) optical design. The convex surfaces of two plano-convex aspheric lenses are arranged oppositely, which can completely eliminate deformation aberration and achieve Edge-to-edge zero aberration and macular aberration. Patients with local lesions can use their good peripheral vision to see, ensuring that all visual fields present a clear picture. It is also suitable for ordinary users for daily needs such as document reading. You can choose from five magnifications: 4.5x/14D/50mm, 3.8x/11.3D/60mm, 2.9x/7.4D/75mm, 2.4x/5.6D/85mm, 2.7x/6.8D/90x50mm. The perfect combination of German-made quality and advanced optical technology gives you a more comfortable visual experience in reading and life. https://www.hwatang.com.tw/uploads/editor/Eschenbach/mediplanergo-set-pl2.jpg **feature of product** **Aplanatic parfocal aspheric lens design** https://www.hwatang.com.tw/uploads/editor/Eschenbach-icon/Aplanatic-Lens-S2.jpg The Aplanatic parfocal aspheric (also known as aspherical) magnifying glass, specially designed by Eschenbach Optics Institute of Ergonomics in Germany, arranges the convex surfaces of two plano-convex aspheric lenses oppositely, so the magnifying glass surface will present a completely flat, precisely calculated light path. It can be directly penetrated. Although the combined magnification is low, it has the advantages of no spherical aberration and no distortion in the field of view. Reading newspapers, magazines, books and other flat printed materials can achieve excellent results. **PXM optical grade Acrylic high transmittance lens** https://www.hwatang.com.tw/uploads/product/H1505/PXM-S2.jpg The patented optical-grade Acrylic lens exclusively developed by Eschenbach in Germany is extremely lightweight and shatterproof, has high light transmittance and sharp imaging. It is an optical product with ergonomic design and excellent effect. https://www.hwatang.com.tw/uploads/product/H1505/PXM-PL2.jpg **Duplex antistatic coating** https://www.hwatang.com.tw/uploads/editor/Eschenbach-icon/DUPLEX-S2.jpg The surface of the lens is treated with antistatic coating to reduce fogging inside the lens. **Precautions** 1. Do not place the lens in the sun when it is exposed to avoid danger. 2. The magnifying glass is an optical aid, used to assist vision. It is not a medical product. If you have eye diseases, please go to an eye hospital for treatment. 3. The best effect can be obtained when using the lens within the focal length (working distance) and eye distance. However, the specifications are the original factory standard data, and the actual situation may vary slightly due to different personal vision conditions. 4. When wiping the mirror surface, do not wipe it vigorously back and forth, as it may still cause scratches on the mirror surface and affect the field of vision. You should first wipe it gently with a damp cloth in one direction, and then wipe it dry with a dry cloth. 5. Do not use volatile detergents to wipe the lenses of this product, as it will cause damage to the lenses. **product specifications** Original factory number: 2668950 Magnification: 2.7x Diopter: 6.8 Dpt Mirror size: 90x50mm Lens material: PXM optical grade Acrylic high light transmittance lens Lens type: Aplanatic parfocal aspheric (aplanatic) lens design Lens coating: Duplex antistatic coating Focal length: 14.7cm Recommended viewing distance: 10~13.5cm Eye distance: 220mm Dimensions: length 204x width 107x thickness 24mm Weight: 138g Origin: Germany **brand introduction** https://www.hwatang.com.tw/uploads/editor/Eschenbach/eschenbach-logo2-M4.jpg?1501828202782 Eschenbach Optical, Germany, founded in 1913, is a leading German manufacturer of vision aids in the world.
