If you search Reddit for opinions on blue light glasses, two patterns show up quickly. Optometry professionals are broadly skeptical that the lenses do anything for screen-related eye strain, while a smaller group of users report that wearing amber-tinted versions in the evening seems to help them wind down and sleep. Both camps tend to agree the marketing oversells the product. That mostly matches the research, which we cover in detail in our guide to what the science actually says about blue light glasses.
What opticians and optometrists say
On r/optometry, the tone leans skeptical. In a thread asking whether blue light lenses are a marketing ploy or a real benefit, several optometrists and optical staff say they do not push the coating because there is no peer-reviewed evidence it protects the eyes or reduces strain. A common caveat: for patients prone to headaches, some clinicians say there may be a small benefit worth trying, but they will not steer people toward it otherwise. A few also mention practical downsides, like a faint yellow tint and blue reflections that show up on video calls.
A separate thread asking if clear-lens blue light glasses are “fake” draws a similar response. Redditors note the tint is real but subtle, that a clinic can test whether a lens actually filters blue light, and that an anti-reflective coating tends to do more for everyday screen comfort than a blue light filter does.
Where the anecdotes turn positive: sleep
The more favorable reports cluster around evening use and sleep, not eye strain. In a r/Biohackers discussion on whether the glasses help before bed, commenters say the amber or orange lenses seem more effective than lightly tinted ones, and that total light exposure matters as much as the glasses. Several point out that dimming your screen and cutting light in the hour before bed does more than the lenses alone. One user in another thread described the glasses as the thing that finally helped their insomnia, while carefully labeling it a personal “n=1” result rather than proof.
Read together, Reddit’s practical takeaway lines up with the evidence: treat blue light glasses as, at best, a minor evening sleep aid, not a cure for tired eyes from screen work. The studies behind that conclusion, and the habits that actually reduce digital eye strain, are in the pillar guide linked above.

I grew up inside an optical shop. My mother likes to tell how, as a kid, I would watch eyeglasses being assembled, play with the tools, and draw on the back of service order slips. The family business taught me early what a precise measurement and work done right are worth.
I went on to spend more than twenty years as a software engineer, always keeping an eye on the optical world. Optogrid was born where the two meet: digital measurement technology (pupillary distance and fitting heights) built by someone who knows the dispensing counter from the inside.
