Electric field distribution and SAR inside a human eye exposed to VR glasses

Abstract

The aim of this study is a numerical analysis of the electric field and the specific absorption rate (SAR) distribution within a realistic 3D‐human eye model exposed to electromagnetic (EM) wave of virtual reality (VR) glasses at the frequency of third generation, long‐term evolution‐4G, and the frequency of the latest generation of mobile networks – 5G. To obtain the values of the electric field and SAR, the numerical solution of equations of EM waves propagation has been used. A new realistic 3D‐human head and human eye model has been created. The obtained results are shown for different biological tissues of the eye exposed to EM radiation from VR glasses at different frequencies. The maximum absorption of EM energy will be discussed for the following frequencies: 900 MHz, 2.6 GHz, and 28 GHz. The maximum values of electric field strength in the human eye tissue at the frequencies 28 GHz and 900 MHz are 94.43 and 137.3 V/m, respectively (higher than referent values), whereas for 2.6 GHz amounts 8.62 V/m (lower than referent limits). The obtained SAR peaks do not overcome prescribed safety values.

“…Likewise, the majority of previous studies used a 2D human eye model and a plane wave as the EM radiation source [8,9]. However, some studies used a 3D model of the human eye to examine the impact of EM radiation from mobile phones and other mobile devices [10,11].…”

“…Over the past years, our laboratory has focused on studying the health effects of exposure to sources of electromagnetic fields ELF (high voltage cable, power plant, transformer station) and HF RF such as mobile phones, their base stations, and wireless communication [1][2][3][4].…”
