Scientific literature indicates that infrared radiation and LED illumination can pose safety risks to human vision under certain exposure conditions, particularly regarding lens opacification and retinal hazard limits at close range.

The analysis

The provided papers collectively support the claim that infrared radiation and infrared-emitting diodes pose potential safety risks to human vision. Paper 0 establishes that infrared exposure can induce acute lens changes (cataracts) in animal models, supporting safety limits. Paper 2 analyzes retinal hazards from close-in LED illumination, highlighting scenarios where hazard levels must be carefully evaluated against international standards.
