In response, the FCC began testing some phones itself rather than relying solely on manufacturer certifications. [37] Microwave and other radio frequencies cause heating, and this can cause burns or eye damage if delivered in high intensity, [38] or hyperthermia as with any powerful heat source.
The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
Cell phones with hearing aid compatibility are less likely to have noise from interference, which makes it easier to hear on the phone. Cell phones have an M rating to denote interference ...
Long-term use of PMMA or thick hydrogel contact lenses have been found to cause increased eye irritability, photophobia, blurred vision, and persistent haloes. [18] There is some evidence to show that rigid gas permeable contact lenses are capable of slowing myopic progression after long-term wear. This same effect was not found in patients who ...
Over the last 10 years, you may have heard rumblings about whether the radio waves emitted from your cell phone are capable of causing cancer. Now, a new review commissioned by the World Health ...
A new study in the Journal of Epidemiology and Community Health shows that children who use cell phones regularly are more likely to have behavioral problems. The review was based on information ...

Diagnosis of the cause of a hearing loss is carried out by a specialist physician (audiovestibular physician) or otorhinolaryngologist. Hearing loss is generally measured by playing generated or recorded sounds, and determining whether the person can hear them. Hearing sensitivity varies according to the frequency of sounds.
