Lasers damage biological tissue in 2 ways, thermal (heat damage) and photochemical which is similar to sunburn caused by guess what high frequency light. There is also acoustical damage which is essentially thermal causing shockwaves from tissue vaporization [1]. Remember higher frequencies have more photon energy leading into ionizing radiation at UV and above? Below a certain frequency all damage is THERMAL. Radio waves are much lower frequency and therefore the ONLY KNOWN mechanisms for biological activity is thermal but you seem to dispute that. And yes it is true you will not get significant ocular heating unless next to a high power radio tower. This will not occur a 100w ham radio levels as you said and certainly won't occur from cell phones 3 orders of magnitude lower than that. 1. https://ehs.princeton.edu/book/export/html/363 https://ehs.princeton.edu/book/export/html/363
