Interaksi antara mata manusia dan gelombang elektromagnet (EM) dalam jalur frekuensi ISM (industri, saintifik dan perubatan) disiasat dengan menggunakan kaedah domain masa perbezaan terhingga (FDTD). Untuk menilai kemungkinan bahaya kesihatan, kadar penyerapan khusus (SAR) dikira dan dibandingkan dengan piawaian keselamatan yang disyorkan. Khususnya, kami mengira kenaikan suhu dalam mata manusia untuk menilai kemungkinan pembentukan katarak yang disebabkan oleh gelombang mikro. Keputusan menunjukkan bahawa nilai maksimum purata SAR adalah kurang daripada tahap standard. Di samping itu, kami memerhatikan apa yang dipanggil 'titik panas' di kawasan humor mata pada 2.4 GHz tetapi tidak pada 900 MHz dan 5.8 GHz. Tambahan pula, kenaikan suhu maksimum disebabkan oleh kejadian ketumpatan kuasa EM sebanyak 5.0 mW/cm2, iaitu had MPE (pendedahan maksimum yang dibenarkan) untuk persekitaran terkawal, didapati paling banyak 0.26

Abstract: The interaction between the human eye and electromagnetic (EM) waves in the ISM (industrial, scientific, and medical) frequency bands is investigated with the use of the finite-difference time-domain (FDTD) method. In order to assess possible health hazards, the specific absorption rates (SARs) are calculated and compared with the recommended safety standards. In particular, we calculate temperature rises in the human eye to assess the possibility of microwave-induced cataract formation. The results show that the maximum values of averaged SARs are less than the standard levels. In addition, we observed what is called the 'hot spot' in the region of eye humor at 2.4 GHz but not at 900 MHz and 5.8 GHz. Furthermore, the maximum temperature rise due to the incident EM power density of 5.0 mW/cm2, which is the MPE (maximum permissible exposure) limit for controlled environments, has been found to be at most 0.26
