DHA destruction from sun?

    I read the study “
    Retinal Light Damage: Mechanisms and Protection”

    It states that DHA can be destroyed from bright light in general. How is the sun less damaging to DHA in retina than blue light on its own?

    Thanks

    Read carefully. What is bright light in this study? What is its composition ? What is the sequence of events as far as changes are concerned in the sun's progression? What does red light do ? How does the Bazan effect play into this ?

    They used artificial light in those experiments. Neither of those experiments were done with natural sunlight. Red in natural sunlight mitigates potentially damaging effects of strong blue light

    Blue light toxicity is amplified in the absence of red light.

    And conversely - reducing blue light reduces the intensity

    Those experiments were done in mice, humans are much more sensitive to damaging effects of blue light compared to nocturnal animals

    Thank you everyone for the replies. I feel everytime i ask a question on this forum i learn a massive amount. Since discovering Dr. Kruse and mitochondriacs ive been intensely curious.
