The correct way to use a magnifying glass:

Hold the magnifying glass in your right hand so that the lens is parallel to your line of sight. Hold the object you want to see and slowly approach the lens to find a clear position. In order to get a larger field of view, keep your eyes as close to the lens as possible, and the effect will be obvious!

Safety precautions when using a magnifying glass microscope:

1: Do not place the magnifying glass in a place exposed to direct sunlight to avoid causing a fire.

2: Do not use a magnifying glass to observe the sun to avoid eye burns.

3: Do not use alcohol, gasoline, and other chemical liquids to wipe the lens and housing.
