Regarding melatonin supplementation:

    Taking melatonin orally chronically without blocking blue light can lead to eye damage. My PSA for the day.

    Makes sense. Supplemental melatonin would make the eyes more sensitive (melanopsin) and blue light is toxic.

    Then, what is the answer for people like me who wear glasses and have IOLs in both eyes.
    For a little over a year I've found that a timed-released melatonin with 5-HTP greatly improved my sleep and reduced my day-time sleepiness.
    I've stopped taking it and now those symptoms are starting to come back.
    I'm sure that my workplace is flooded with blue light and when I've worn blue-blocking eyewear there I seem to feel more sleepy/tired.
    What are the best bio-hacks for my situation?
    Feed-back is greatly appreciated.

    Thank you.

    This post is all about melatonin fundamentals.

    True friendship is like fluorescence, it shines better when the situation darkens.

    NEW SUNDAY BLOG OUT: Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore lower energy, than the absorbed radiation. The most striking example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the spectrum, and thus invisible to the human eye, while the emitted light is in the visible region, which gives the fluorescent substance a distinct color that can be seen only when exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after.

    Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labeling, dyes, biological detectors, cosmic-ray detection, and, most commonly, fluorescent lamps. Fluorescence also occurs frequently in nature in some minerals and in various biological states in many branches of the animal kingdom.
