ResumoWe report on the effects of RF (radiofrequency) radiation emitted by cellphones, on the efficiency of human eyes as affected by the thermal effects of this low frequency electromagnetic radiation.A number of 68 volunteer students from the faculty of optometry at Al-Neelain University, Khartoum, Sudan, were randomly selected for the purpose of this study.The ages of tested students ranged between 18 and 25 years, none of which complain of sight complications (vision or refraction).A questionnaire combined with vision and refraction tests was applied.It was found that apart from which side of the head cellphone was used, the majority (80%) complain no problems with vision acuity test, but in the contrary approximately 90% showed to complain from defects in refraction for both eyes.It was concluded that defects in the refraction of human eyes could be attributed to thermal effects of RF radiation emitted from cellphone during phone calls.Reduction of call duration when using cellphone in direct contact with the head was recommended.
