Electric field distribution and SAR inside a human eye exposed to Virtual Reality glasses
Abstract
Overview
This study conducts a numerical analysis focusing on the electric field and specific absorption rate (SAR) distributions within a 3D-human eye model exposed to the electromagnetic waves from virtual reality (VR) glasses.
Methodology
- A realistic 3D-human eye model is exposed to EM waves from VR glasses operating at various frequencies.
- Frequencies examined include 900MHz, 2.6GHz, and the 5G band at 28GHz.
Key Findings
- The maximum electric field strengths detected were 94.43 V/m at 28GHz and 137.3 V/m at 900MHz, suggesting potential safety concerns as these values exceed referent limits.
- Conversely, at 2.6GHz, the electric field strength is 8.62 V/m, which is below safety thresholds.
- The SAR values did not exceed safety limits, but the high electric field strengths imply a potential risk.
Conclusion
The implications of different frequencies on eye tissue vary, but the high electric field values at certain frequencies reveal a need for further investigation into potential health risks associated with the use of VR glasses.
