Are some barcode scanners at supermarkets dangerous for the eyes?

Question

I was at my local supermarket tonight where they have large built-in barcode scanners fixed in an upright position underneath the touch screen that the cashiers work on. They have a separate unit for the cash register and another screen on top of it for the customer to see the products going through.

As I was waiting on the opposite end of another cashier where an employee was working, I noticed laser lights coming out of the barcode scanners screen which is fairly large, and it was shining in my eyes and I looked into it several times.

I’m not too familiar with the danger of lasers and was just concerned if the laser light from some of these large supermarket barcode scanners could be damaging to the eyes? I’m only asking because my eyes are feeling discomforted and that could be unrelated to this. Thank you

Yes they are, but you'd  have to look at them for a lot more time. That with your eyes is normal if you look at a laser.
