Microwave radiation above 1.0 mW/cm² damaged rabbit eye lens proteins and caused opacity, suggesting WiFi-frequency EMF may contribute to cataract formation.

Plain English Summary

Summary written for general audiences

Researchers exposed rabbit eye lenses to microwave radiation at 2450 MHz (the same frequency as WiFi and microwave ovens) for 8 hours at various power levels. They found that exposure levels of 1.0 mW/cm² and higher caused the lens proteins to change structure, leading to decreased transparency and cloudiness that could impair vision. The higher the exposure level, the more severe the protein damage and opacity became.

Why This Matters

This study provides concerning evidence that microwave radiation can directly damage the delicate proteins in eye lenses, potentially leading to cataracts. The 2450 MHz frequency tested is identical to what WiFi routers, smartphones, and microwave ovens emit. While the 8-hour continuous exposure used here is longer than typical device use, the power densities that caused effects (starting at 1.0 mW/cm²) are within range of what people experience from close proximity to wireless devices. The research demonstrates a clear dose-response relationship, meaning higher exposures caused progressively more damage. What makes this particularly significant is that lens proteins don't regenerate like other tissues, so damage accumulates over time. This adds to growing evidence that our eyes may be especially vulnerable to microwave radiation, warranting more protective exposure guidelines.

Microwave radiation higher than 1.00 mW/cm(2) can affect the proportion of WSP and USP in cultured rabbit lens, and cause changes of lens transparency and refractive power, which leads to lens opacity.
