Abstract

Overview

This paper presents a numerical study assessing the impact of electromagnetic radiation from wireless eyewear devices on human ocular tissues. The focus is to understand how prolonged exposure can affect eye temperature and suggest potential health implications.

Findings

• The temperature in the eyeball increases over time, potentially reaching thermal steady state in approximately 30 minutes.
• Temperature increments between 1.1°C and 1.7°C were observed across different ocular tissues.
• Significant temperature rises, to 42.9% and 69.2% of the final steady-state value, occur within the first 5 and 10 minutes respectively.
• These results suggest that prolonged exposure to electromagnetic fields from these devices could pose a threat to eye health, notably so for the lens.

Conclusion

The study indicates a link between wireless device usage and potential ocular damage and advises reducing exposure duration. It also highlights the non-linear relationship between maximal SAR and temperature increases, suggesting that both factors should be considered in safety evaluations. This study could inform future safety standards and research on biological effects of microwaves on eyes.
