The importance of investigating the health effects of RF radiation on the cornea cannot be overstated. This study aimed to address this need by utilizing a mathematical simulation to examine the absorption of millimeter wave (mmW) and terahertz (THz) waves by the cornea, considering both normal and pathological conditions. The simulation incorporated variations in tear film thickness and hydration levels, as these factors play a crucial role in corneal health. To assess the impact of RF radiation on the cornea, the study calculated temperature rises, which indicate heating effects for both dry and normal eyes. XFdtd, a widely used commercial software based on the Finite-Difference Time Domain (FDTD) method, was employed to evaluate the radiation absorption and resulting temperature changes. The outcomes of this study demonstrated a crucial finding, i.e., that changes in the water ratio and thickness of the tear film, which are associated with an increased risk of dry eye syndrome, directly impact the absorption of mmW and THz waves by the cornea. This insight provides valuable evidence supporting the interconnection between tear film properties and the vulnerability of the cornea to RF radiation.
研究射频辐射对角膜健康影响的重要性怎么强调都不为过。本研究旨在通过数学模拟来满足这一需求，以检查毫米波及太赫兹波在正常和病理条件下被角膜吸收的情况。该模拟考虑了泪膜厚度和水合水平的变化，因为这些因素对角膜健康起着至关重要的作用。为了评估射频辐射对角膜的影响，本研究计算了温度升高，这表明干燥和正常眼睛都有加热效应。XFdtd 是一种广泛使用的基于时域有限差分法 (FDTD) 的商业软件，用于评估辐射吸收和由此产生的温度变化。这项研究的结果表明了一个关键发现，即与干眼症综合征风险增加相关的泪膜水比和厚度的变化，直接影响了角膜对毫米波和太赫兹波的吸收。这一见解为泪膜特性与角膜对射频辐射的脆弱性之间的联系提供了有价值的证据。
