Plain English Summary
Researchers exposed rats to WiFi-level radiation (2.45 GHz) for 2 hours daily over 21 days. They found the front layer of the cornea became significantly thicker in exposed rats compared to unexposed ones, suggesting everyday wireless device radiation may cause structural eye changes.
Why This Matters
This study adds to growing evidence that EMF exposure affects more than just the brain and reproductive organs. The fact that researchers found measurable changes in corneal structure at a SAR of just 0.25 W/kg is particularly significant. To put this in perspective, this exposure level is well within the range of everyday wireless device use, similar to what you might experience from a WiFi router or smartphone during extended use. The cornea is one of the body's most sensitive tissues, and any structural changes could potentially affect vision or eye health over time. While this was a preliminary animal study, it joins dozens of other studies showing that current safety standards may not adequately protect against non-thermal biological effects. The reality is that our eyes are constantly exposed to these frequencies through our wireless devices, and this research suggests we should take that exposure seriously.

Where This Falls on the Concern Scale
Study Details
To investigate the effects of low level electromagnetic field (low level-EMF) exposure, as frequently encountered in daily life, on the normal rat cornea using histological and stereological method.
Twenty-two adult male Wistar rats were randomly divided into two groups: Study group (n = 11) and co...
Using the histological method, the mean corneal thicknesses in the control and study group were 278....
Results of this preliminary study show that exposure to MW radiation might cause alterations in the rat cornea.
