GSM phone signals showed no immediate effects on visual sensitivity at realistic exposure levels during short-term testing.

Plain English Summary

Summary written for general audiences

Researchers exposed 33 people to GSM mobile phone signals near their eyes to test whether radiofrequency radiation affects visual sensitivity (the ability to detect light differences). Using exposure levels similar to holding a phone close to your face, they found no measurable changes in visual discrimination abilities during 30-minute exposure sessions. This suggests that typical mobile phone use doesn't immediately impair basic visual function.

Study Details

The aim of this study is to investigate Influence of a 902.4 MHz GSM signal on the human visual system: investigation of the discrimination threshold.

The VDThr was measured for 33 subjects under standardized conditions. Each subject took part in two ...

No statistically significant differences in the VDThr were found in comparing the data obtained for ...
