# WEB-032 — 60 GHz: eye injury under different temperature and humidity conditions

Why this matters
An eye’s response to strong exposure may depend on its surroundings as well as the field itself. This study examined those conditions directly. The injury findings belong in the record, alongside the uncertainty in the additional effect attributed to heat and humidity.

Topic: Ocular effects and corneal injury; 60 GHz-region biological responses; Environmental modification of injury thresholds

Verification Group: Original abstract reviewed

Record Role: Original abstract reviewed

Featured: False

Exposure: 60 GHz; 200 or 300 mW/cm² for 6 min; ambient 24°C/50% RH, 45°C/20% RH or 45°C/80% RH.

Design: Rabbit exposed-right/unexposed-left eye comparison; corneal staining, opacity, thickness and temperature endpoints.

Finding: Ocular injury was associated with incident intensity. Hotter, more humid conditions tended to worsen damage, but that additional environmental effect was not statistically significant.

Statistics: See the original results; effect sizes were not independently recalculated.

Boundary: Original abstract only; sample size and full methods not audited. High-intensity thermal-injury conditions. Do not present the humidity trend as an established independent effect.

Related: Japanese ocular research programme with WEB-012, WEB-022 and the 2026 tissue-model report. Related publication records: WEB-033.

Protection Question: Which exposure conditions reproduce this finding, and what would establish its relevance beyond the experimental model?

Access: Original abstract and bibliographic identity reviewed; full methods, dosimetry and statistics not audited.
