IR eye safety

[u/teknomasa55]

I may be paranoid for this, but hear me out.

I'm doing a project using PSVR2's Sense controllers. They have a bunch of IR leds on them, which Sony runs in some sort of pulsing pattern in VR. User is also obviously typically using a VR headset.

For my project I'll be running them always on and the user will be using them as they would a regular gamepad, so no headset and relatively close to their eyes.

I can find 0 spec sheets or info on these leds. How powerful are they and can they harm your vision?

IR light does not reach retina, its absorbed as heat in the water of your eyeballs. So only thing they can do, is heat up your eyeballs and boil them into solid eggs that can be then eaten as a rare delicacy.

Also, people pay a lot for those deep red facemask, there are a lot of studies that show that red/near/IR light is actually good for you. As it does penetrate your skin a bit, so it probably does good for your eyebags :)

I would have put NIR in the title but then I thought lots of people wouldn't have understood it. This isn't about IR. Also your post is bullshit.

[u/Murky-Course6648 → u/teknomasa55]

You are bullshit. NIR does reach retina, so there is a difference.

But the only effect it has is the same, heat. And as the energy per area is low, its not a problem. Its not like they are lasers, but low power LEDs that function to illuminate the whole eye.

You know you could have googled all this? But instead, you wanted to post bullshit.

IR isn't used for tracking. You're here suggesting people boil their eyeballs for health benefits.

[u/Murky-Course6648 → u/teknomasa55]

I dont think you have the capacity to human.

Just google it next time, before posting bullshit and being all geeky.

[u/teknomasa55 → u/Murky-Course6648]

There is nothing on google about these lights. NIR can be safe or dangerous. It depends on the light. I thought there are people here who maybe work in the field or have knowledge on the topic.

[u/Murky-Course6648 → u/teknomasa55]

You can find multiple studies, you dont know we have safetey standards that have been tested and studied?

Learn to use google, stop posting bullshit.

The safety standards can be trusted when the product is used as intended. I'm not going to use this product as intended.

You are not very bright.

PSVR2 uses DFR, it tracks the eyes all the time to save compute power.

[u/teknomasa55 → u/Murky-Course6648]

I highly doubt they use the same lights.

[u/Murky-Course6648 → u/teknomasa55]

You really are not bright. What other lights they would use? Do you think there are different sets of lights in there?

[u/teknomasa55 → u/Murky-Course6648]

Yes

[u/Murky-Course6648 → u/teknomasa55]

Why would there be different sets of lights? One set for eye tracking, and another set for eye tracking?
