IR light safety?

I believe Wyze cams use 850nm IR LEDs. I’m curious if anyone is aware of any research on the safety of long-term exposure to IR light, especially when the camera is used as a baby monitor (which might only be a few feet away from the baby for hours at a time)? Is anyone aware of any research on potential health concerns, especially with regards to eyesight? My wife and I are expecting our first baby in August so I figured I would double-check.
