The BOM[0] specifies that this is a "3mw 780nm Infrared IR Diode Laser" with a link to eBay[1].
I'm finding 780nm 2.5mw and 3mw laser diodes rated at classes 3B and 3R. See [2] and [3]. The 3B class rating is given for a high end Edmund Optics laser which most probably gives out the "full" 3mW. A 3B class laser is "hazardous for eye exposure" [4].
So... hard to say, but not great?
I fondly remember a sticker that was on a lab's (very scary) laser: "Do not look into laser with remaining eye"...
