just look up 'welders eye' or 'corneal flash burns' or 'photokeratitis'
high intensity UV light most certainly causes both corneal and retinal damage, both acute and as an ongoing effect over time.
i have never seen nor can i find any reference to visible blue light. i think* that heavily phosphored leds with high CRI and low color temp do emit quite heavily above visible and translate it down. so maybe there is some leakage?
No one disputes that sufficient light can damage the eye. The question is whether there's any evidence that LEDs cause damage to the eye sure to the higher percentage of blue light.
The fact that exposure to extreme amounts of light can damage the eye is not evidence for the claim that LEDs at typical brightness damage the eye.
