Recently, the French health authority warned that LEDs can permanently damage our eyes because of their blue light levels. Other studies also showed that blue light exposure from LEDs may increase the risk of age-related macular degeneration. https://www.dailymail.co.uk/health/article-7032303/LED-lights-irreversibly-damage-eyes-French-health-authority-warns.html

Interestingly, they didn't really compare LEDs with sunlight. Does that mean sunlight is safer even though it's much more intense?

In an office, you would expect the lighting level to be around 500 lux, and in sunlight, you can expect 1000 to 100,000 lux depending on the sun's angle and cloud over. My assumption is that sunlight would have more blue light for a given area. enter image description here

If sunlight really is safer, I think it's because people protect their eyes in the sun because of the glare. They may squint, spend less time outside, wear sunglasses, or seek shades.

    Your source is a brief press article that summarizes a 400-page report. How sure are you it accurately reflects what the French study actually said? Maybe the report did consider sunlight but the journalist just failed to mention it. Finding the actual report online would be a huge improvement to your question. – Carey Gregory Jul 22 '19 at 3:58
