The HU-20 BigEye™ 2x Power Magnifier with Oversized 5.0 inch Distortion-Free Lens has a 5″ over-sized viewing lens and is likely the biggest of any Hand Held Magnifier available! It may be oversized yet it is still lightweight thanks to its high quality crystal-clear acrylic lens. The BigEye™ is perfect for viewing just about anything…including insects, rocks, foliage or anything found in nature.
