Blue light glasses are heavily marketed as sleep aids. The research is mixed. Here is the honest answer.
What blue light actually does
Blue spectrum light suppresses melatonin production. Daytime exposure is fine. Evening exposure delays sleep onset.
Do blue light glasses help?
- Marginal effect. Studies show small improvements in melatonin levels with blue-blocking glasses.
- Not as effective as removing screens entirely.
- Most-effective if worn 2-3 hours before bed.
Better alternatives (free or near-free)
- iPhone Night Shift / Android Night Light (free, built-in).
- f.lux for computers (free).
- Use phone in greyscale mode evening.
- Read paper book instead of screens.
- No screens 30-60 min before bed.
If you do buy blue light glasses
Look for amber-tinted lenses (block more blue spectrum than clear “blue light” glasses). $15-$40 on Amazon.
Verdict
Blue light glasses provide marginal benefit. Free phone settings (Night Shift) help more. Removing screens entirely 30-60 min before bed is most-effective.
