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.
There are handheld bar code scanners, so a handheld bar code scanner is a bar code scanner, but a bar code scanner is not necessarily a handheld scanner. There are bar code scanners in store checkout stands that are fixed, and there may or may not be an associated handheld scanner there for the clerk to use to scan, say, a large bag of dog food that the customer doesn't want to hoist up onto the counter.
