How to use

Hold the magnifying glass at a comfortable distance from the eye and position the lens over the object to be examined. For text, move the lens closer or farther from the material until the image becomes sharp; with a 3× lens this distance is typically a few centimetres. Use steady, small movements to scan larger areas and keep the lens perpendicular to the surface to reduce distortion. Store the magnifier in a dry place when not in use to keep the lens clean and scratch-free.

Usage recommendations

Clean the lens with a soft, lint-free cloth and, if needed, a small amount of lens cleaner. Avoid abrasive materials and excessive pressure. For prolonged inspection tasks, rest the forearm on a stable surface to reduce hand shake and improve viewing stability.
