Radiofrequency (RF) energy causes various side effects including cataracts and have some undesirable effects on retina and cornea. However it is still uncertain whether the amplitude-modulated RF signals from digital phones exert similar bio effects compared to that of continuous (unpopulated) RF radiation though the increase use of cellular phone generate concern to health. The purpose of the study is to assess the impact of RF radiation emitted by smartphones on dioptric power of the eye. Total 50 healthy male and female adult volunteers were recruited for this study between the age group 18-40 years. The Dioptric value of the subjects was recorded prior to study. After an interval of 30 days, the Dioptric values were recorded again for the assessment. Similarly, Visual acuity, Retinoscopy readings and keratometer reading were recorded. The study suggests that there are certain changes in parameters in the subjects after exposure to RF radiation. We can conclude prolonged use of smartphones in daily life may have a negative effect on the eyes and dioptric values changes with higher exposure to RF.
