The effects of microwave radiation generated by mobile phones on the tear film

Abstract Electromagnetic radiation (ER) emitted by mobile phones and other modern devices has potentially harmful effects on ocular tissue. Their effects on the eye surface and tear film are little known so far. The aim of this paper was to investigate the effects of ER emitted by the phone mobile on the tear film. For this study, we selected a total of 50 subjects, young, healthy, without chronic treatment, who are not contact lens wearers and who have no history of ophthalmic surgery. Schirmer I test, tear pH and tear ferning test (TFT) were performed on all subjects before (“-pre”) being exposed to ER emitted by the mobile phone and after (“-post”) exposure for 5 minutes, the pH and TFT …
