30x Portable Magnifying Glass: The magnifying glass is made of high-quality double-layered optical glass (not resin or acrylic glass), which is more scratch-resistant and has excellent clarity. Actual optical magnification up to 30x (3000%) and a 4 \" objective lens provide a wider field of view, so even very small print can be clearly magnified, allowing visually impaired seniors to easily read text, regardless of size. 【NEW VERSION】 18 Super Bright LEDs with 3 Modes: Built-in 18 energy-efficient LEDs provide extra brightness, ensuring a better reading experience even at night or in dark places. 3 dimmable light modes (cool, warm, mixed) can be switched depending on different lighting conditions, which can reduce visual fatigue and is very useful for patients with macular degeneration. Easy One-Touch Operation: The BUSATIA magnifying glass comes pre-assembled and requires no batteries. The LED light source is controlled by a four-stage push button, which is controlled by a simple ON/OFF button. Just insert 3 AAA batteries and press a button, and you're ready to play again. Easy to use, suitable for seniors and children. NOTE: Batteries are not included. PERFECT GIFT FOR SENIORS AND CHILDREN: The BUSATIA illuminated magnifying glass is ideal for seniors who have difficulty checking instructions, receipts, prescriptions, medicine bottles, and small text for reading books, newspapers, magazines, etc. It is also useful in children's science lessons and nature excursions to spark their curiosity about the outside world.
