Your Eyes and Cell Phone Damage

Many years ago, perhaps in the mid 90s, an attorney I know, and a HAM radio operator, was talking with me about EMF. He pointed out that for a very long time the FCC has had on its licensing exam a question regarding the fact that EMF (radio waves) are a known cause of cataract.

This article looks at the issue again and also points out the importance of keeping the cell phone as far away from you as possible.

This is the same concern in regard to cell phone effect on your thyroid gland and function.

Cell phones can damage eyes: Study
Prashant Rupera, TNN, Jun 23, 2010

VADODARA/ANAND: While scientists across the globe are still debating whether usage of cell phones results in heart diseases, a new study carried out by scientists at Charotar University of Science and Technology (CHARUSAT) has revealed that mobile phones also affect eyes.

The scientists, who have studied the impact of electromagnetic waves on human eye, say that usage of mobile can also lead to early cataract in lens apart from affecting retina, cornea and other ocular systems of the eye.

"We are in ocean of electromagnetic signals and hundreds of signals are hitting human body every moment. It is affecting all our body parts, but we are not realising it," says professor Ved Vyas Dwivedi, head of department of ECE at CHARUSAT, who along with dean of the faculty of engineering and technology Y P Kosta and lecturer Dhara Patel carried out the study based on a mathematical model.

"The wavelength of wireless signals (which is about 2 to 2.5 cm) used for mobile phones and other wireless terminals matches with that received by the human eye. The dielectric constant (absorption capacity) of eye tissues is around 70 which is greater than unity (above 50). This means that the eye can absorb electromagnetic energy very quickly," explains Dwivedi.

During the study, scientists computed the specific absorption rate (SAR) and maximum temperature increase in the eye because of electromagnetic radio frequency fields generated by wireless terminals such as a mobile phones. SAR and temperature rise depend on the distance between eye and radio frequency transceiver (the mobile phone) and the angle between the line of sight and shortest normal path.

"The problem is not that the eye absorbs the energy, but that the heat absorbed by the eye does not get transmitted or radiated out of the body," says Dwivedi, adding that prolonged usage of mobile phones can affect retina, sclera, lens, cornea as well as vitreous humour which are parts of the human eye.

These scientists have also recommended that a mobile handset should be kept as far as possible from the eye. "It should not be used more than is necessary. A user should avoid use of mobile in rural areas or a car where the cell phone uses more power and the SAR value can be ten or hundred times higher than the normal," they suggest. This group of scientists is also planning to approach the government in collaboration with a hospital to get license to conduct tests on human to further study mobiles affect on human eye.

Oh no! What next will scientists discover about the damage of new technology?

Thankyou for this very information post about cell phones and our eyes!

This was a very vital facts that everyone should know. Cellular phones having a microwave frequency can cause a radiation damage in our body, specifically on our eyes. According to Arizona eye care, the heat that is being stored through absorbing radiation may cause eye problems in a long run. This study was proven on 1940's and yet it was hidden by these mobile providers to cover up for the loopholes.

Great post! Been reading around for different opinions on this. Thanks for the info!
