Thirty minutes of GSM radiation showed no immediate effects on light sensitivity, but longer-term eye impacts remain unstudied.

Plain English Summary

Summary written for general audiences

German researchers exposed 33 people to cell phone radiation at 902.4 MHz for 30 minutes to see if it affected their ability to detect light (visual discrimination threshold). They found no statistically significant changes in visual sensitivity between real exposure and fake exposure sessions. This suggests that brief GSM radiation exposure at typical power levels doesn't immediately impair basic visual function.
