I think you're right. There was just an article about blue light speeding blindness, but the flux author chimed in and said screens are less than 5% of the hazard weighted irradiance of the sky. [1]
I'm not totally sure what that means honestly, but I think we're OK.

- TACIXAT 8y agoI did on shrooms once. It had some nice patterns because my pupils were so dilated. Thankfully not blind.
- smolder 8y agoI don't think the patterns are from your eyes behavior mainly but rather misfiring nerves directly thanks to the toxin. Noise transformed by visual circuitry into patterns, as patterns are what it deals in on the perceiving end.
- Rapzid 8y agoShrooms don't cause blindness; the sky causes blindness.
- jdietrich 8y agoIt's kind of obvious to anyone who has used a photographic light meter. My computer screen has a peak luminance of about 300cd/m2. A super bright HDR display can achieve peak luminance of about 800cd/m2, which most people find uncomfortably bright in normal viewing conditions. An overcast sky is about 2,000cd/m2 and a clear sky is about 7,000cd/m2. UV is vastly more damaging than blue light and monitors produce negligible amounts of UV.
