Is it weird? I can see light coming from MM optics

On 850nm MM optics I can see red light. Typical vision is up to 700nm, so I am wondering if there is some other light the SFPs are pushing out, or is it strictly 850nm? Was I bitten by a radioactive spider or is this normal see light out of MM optics? I tried both 1G and 10G optics from Cisco and FS and I can see red on both.
