Can a bar code scanner blind someone?

A barcode scanner emits a low-powered laser or uses LED light to read barcodes, and under normal use, it is not capable of blinding someone. The light intensity is generally safe for the eyes, and the exposure time is minimal. However, staring directly into the beam for prolonged periods could potentially cause discomfort or temporary vision issues, but this would be unlikely to cause permanent damage. Always use barcode scanners as intended to avoid any risks.
