| I found a study within a few seconds on Google Scholar which refutes OP's study. Using google translate, i see this in the article (German translated to English): "According to a recent study, contact lenses that block blue light do not provide better protection from eye fatigue than standard contact lenses than standard contact lenses (American Journal of Ophthalmology 2021; DOI: 10.1016 / j.ajo.2021.02.010), according to the DOG." Hmm... One article versus several: https://scholar.google.com/scholar?hl=en&as_sdt=0%2C44&q=blu... Several studies available at link above. Here's an example from what I found via google scholar query: "All light is not equal: blue wavelengths are the most potent portion of the visible electromagnetic spectrum for circadian regulation. Therefore, blocking blue light could create a form of physiologic darkness. " "At the end of the study, the amber lens group experienced significant (p < .001) improvement in sleep quality relative to the control group and positive affect (p = .005). Mood also improved significantly relative to controls. A replication with more detailed data on the subjects' circadian baseline and objective outcome measures is warranted."
