Magnabrite 89mm, 4x (3.5") Dome Magnifier

The Magnabrite 89mm Dome Magnifier is the larger, best-selling version of the classic Magnabrite dome — a favorite among low vision professionals and their patients for decades. At 3.5 inches across, this generous dome provides an expansive 4x magnification viewing area that makes reading books, newspapers, recipes, and crossword puzzles genuinely comfortable and strain-free.

Like all Magnabrite domes, the 89mm model is carved from optical-grade PMMA acrylic, which transmits approximately 92% of visible light and gathers ambient illumination through its curved surface — naturally brightening the image without any batteries or bulbs. The flat base rests securely on the page; simply slide it across lines of text and the image stays sharp at every point.

Key Features:

• 4x genuine optical magnification — crisp, distortion-free, edge to edge
• Large 89mm (3.5-inch) viewing diameter — ideal for extended reading sessions
• Optical-grade PMMA acrylic — transmits ~92% of visible light for a brilliantly bright image
• Pre-focused, no-adjustment design — place it down and start reading immediately

• No batteries, cords, or charging needed
