What people are saying
The discussions highlight the groundbreaking nature of the research, with comments like 'genuinely impressive' and mentions of the discovery of a 'peak sensitivity' that doesn't match known photoreceptors. The tone varies from technical appreciation to practical advice, such as urging the use of blue blockers at night, reflecting both curiosity and perceived importance of the findings.
Most discussions strongly support the findings, emphasizing the discovery of a new circadian photoreceptor and its implications for melatonin regulation.
The discussions demonstrate high interest, with references to blue light, protective measures like blue blockers, and detailed technical insights, indicating curiosity about the research's significance.
Posts show deep engagement, including sharing practical advice, technical evaluations of light spectra, and noting the impact on health, which suggests meaningful involvement with the topic.
Many recognize the research as highly impactful, discussing its potential to influence health habits and lighting technology, indicating a perception of high significance.
Abstract in brief
- This study aimed to identify the specific light wavelengths that influence melatonin suppression in humans, which is crucial for understanding how the eye regulates our circadian rhythms.
- The results showed that the most effective wavelength for suppressing melatonin is around 446–477 nm, suggesting a single, new type of photopigment in the human eye that is different from the known visual pigments in rods and cones.
- These findings point to the existence of a novel retinaldehyde-based opsin photopigment responsible for circadian light sensing, providing new insights into how light impacts human biological clocks beyond traditional visual pathways.

you can find it here https://t.co/QWuOG2z9Pk -- it is genuinely impressive, and identifies a peak sensitivity corresponding to blue light. This is especially badass because this peak doesn't correspond to any of our well-understood vision-related photoreceptors! WTF! https://t.co/akfB7regU2
@MaartenWijntjes @tsawallis @CurrentBiology The action spectra of human melatonin suppression (https://t.co/7XDGGaSvKp and https://t.co/WNoPdPwxLi measured by @debrajskene) suggest a peak spectral sensitivity at wavelengths shorter than the melanopsin spectral sensitivity (~480 nm). 3/

@JFriederHarmsen Hello Jan-Frieder, In fact is density /cm2 a better measure. Propeaq has 0.6 μW/cm2/465nm which is in between 15 and 35 lx at cornea level, depending on face characteristics. More info on melatonin action spectra: https://t.co/bW2qoBmS1o Regards Toine
