13.7 cm Extra Large Magnifying Glass: Lens material: Acrylic lens Size: 13.7 cm. Our high-quality acrylic lens is lighter and more shatter-resistant than glass lenses while providing the same clarity. The 13.7 cm large lens is large enough to provide a large viewing area without you having to constantly move your hands. A must-have for scientists, professionals, seniors, and people with low vision, macular degeneration, or visual impairment. 3 Illuminated LED Lights: Our reading magnifier has 3 energy-saving LED lights. Even at night or in the dark, the user can have a great reading experience. Especially if you have presbyopia, amblyopia, or macular degeneration, this will be a great choice for you to read the newspaper or books. Ergonomic Handle Design: The handle of the illuminated magnifying glass is ergonomically designed to be comfortable for most hands to grip/hold, making it ideal for anyone who enjoys reading for long periods. Comes fully assembled and only requires 3x AA batteries (not included). Once the batteries are inserted, the magnifying glass with light is ready to use and is perfect for the elderly or those who need an intuitive magnification system. Perfect Gift for Seniors & Children: This reading magnifying glass is the perfect gift for seniors (mom, dad, grandma, grandpa) to read the fine print. Not only can it give children a lot of fun exploring nature, but it can also help seniors check small words, crafts, photos, read books, newspapers, medicine instructions, collect coins and stamps, etc. Due to old age and some eye problems, including macular degeneration, the inability to read small text becomes a significant problem, especially the information printed on a medicine bottle and daily socialization on mobile phones. LED light as an additional light source is the difference between a new magnifying glass and a traditional magnifying glass. Whether for reading or jewelry, our handheld LED magnifying glass which has built-in light can significantly improve the lack of light source during use. You can read the smallest font quickly and easily while reducing eye strain.
