Electromagnetic Exposure Analysis of the Human Eye due to Virtual Reality Glasses

With the development of wireless network technologies, there is a variety and innovation in wearable products. Virtual reality (VR) glasses are one of these innovations. VR glasses usually cover the eyes, which increases the exposure of large areas of that region. In this study, the specific absorption rate (SAR) and the electric field distribution in the eyes of a human model wearing VR glasses operating at the next-generation communication frequency band (2.4 GHz) were modeled and numerically analyzed. Simulations were carried out in a three-dimensional problem space, referencing the actual dielectric values of tissues as described in the literature. The maximum electric field strength in the human eye tissue calculated as 24 V/m. The corresponding maximum SAR value is 2.31 W/kg for 1 g average tissue. These findings provide essential insights into electromagnetic exposure safety requirements for the next generation of extended reality applications, in parallel with technological advancements.
