About MicrowaveExtremely high frequency radio waves, have frequencies (Hz) 3 x 10^9 to 3 x 10^10 and have very short wavelengths ranging from approximately one millimeter to 30 centimeters. Stars also give off microwaves.
Prolonged exposure to microwaves is known to cause "cataracts" in your eyes and preventing you from seeing clearly. Recent research indicates that microwaves from mobile phones can affect parts of your brain.So the advice is to keep calls short.
