Lan JQ, Liang X, Hong T, Du GH. On the effects of spectacles on the SAR inward human caput resulting from wireless eyewear devices at telephone phone band state. Prog Biophys Mol Biol. 2018 February 8. doi: 10.1016/j.pbiomolbio.2018.02.001.
Abstract
This newspaper evaluates the effects of spectacles on the specific absorption rates (SAR) inward the human caput resulting from wireless eyewear device at telephone phone band state. We mainly concentrate on the SAR inward the eyes since their sensitivity to electromagnetic fields (EMF). We notice wearing spectacles apparently alters the distribution too magnitude of the SAR. The maximal SAR inward the ocular tissues amongst spectacles is fifty-fifty half dozen times to a greater extent than than that without glasses. Wearing spectacles also possess the novel hotspot inward the eyes which may crusade the biggest SAR increment inward the ocular tissues. Moreover, calculated results dot that the maximal SAR is sensitive to the size of spectacles too radiations frequency. Because of this, nosotros believe wearing spectacles may peradventure increment the adventure of wellness endangerment to eyes of wireless eyewear device user. These calculated results could endure a valuable reference for the spectacles designer to trim back the SAR inward the eyes.

The Google Glass, an optical head-mounted display designed inward the shape of a twain of eyeglasses, was non embraced past times the full general populace when it was introduced inward 2013-2014. So Google changed its marketing strategy to target specific occupational needs including healthcare, military, too sports applications.

Conclusions
Based on the calculated results, nosotros notice wearing spectacles apparently alters the distribution too magnitude of SAR. The maximal SAR inward the ocular tissues amongst spectacles is fifty-fifty half dozen times to a greater extent than than that without glasses. Wearing spectacles also could possess the novel hotspot inward the eyeballs which may crusade the biggest SAR increment inward the ocular tissues. Moreover, calculated results dot that the maximal SAR is sensitive to the size of spectacles too radiations frequency. Therefore, nosotros believe wearing spectacles may peradventure increment the adventure of wellness endangerment to human eyes. In enterprise to decrease the SAR inward the ocular tissues, people should lead the adaptive spectacles according to the radiations frequency. If possible, nosotros advise people to lead keep off their spectacles when they role the eyewear device. These calculated results could endure a valuable reference for the spectacles designer to trim back the SAR inward the eyes. However, due to the express inquiry conditions, the experiment is non included. So conclusions, inward this paper, are only indicative but non definitive.

Recently, a colleague told me that around physician offices inward California require their staff to wearable the Glass. Last week, National Public Radio reported that around manufactory workers must also wearable the Glass.

Following is a press unloose I prepared 3 years agone which provides precautionary data close this wireless device. SAR values for the latest model of the Google Glass follow the press release.

Google Glass Alert: Potential wellness risks from wireless radiation
The Google Glass emits to a greater extent than wireless radiations than most jail cellphone phones on the market, but different jail cellphone telephone users, Glass users may endure wearing this device on their heads for to a greater extent than than 12 hours a twenty-four threescore minutes catamenia putting their wellness at risk.
By Joel M. Moskowitz, Ph.D., School of Public Health, University of California, Berkeley
BERKELEY, Calif. - April 15, 2014 - PRLog -- The Google Glass emits both Wi-Fi too Bluetooth radiation. Although the Glass official spider web site, http://www.google.com/glass/start/ , contains data warning consumers close the device's potential interference amongst radio or boob tube reception, the site provides no security data to consumers.
As a body-worn, microwave-emitting device, Google is required past times Federal police pull to exam the Specific Absorption Rate or SAR of the Glass. This is a mensurate of the maximum microwave radiations absorbed past times the user inward half dozen minutes averaged over ane gram of tissue.
Although Google did non post the SAR data on its spider web site, the Glass exam reports tin sack endure constitute on the FCC's spider web site at [https://fccid.io/document.php?
The official exam study indicates that the SAR for the Glass is much higher than the SARs for the iPhone 5, the Samsung Milky Way S5, or most jail cellphone phones on the market.
During the final year, Google improved the antenna on the Glass which resulted inward an increment inward the SAR from 1.11 to 1.42 watts/kilogram (W/kg). In contrast, the Samsung Milky Way S5 has a caput too trunk SAR of 0.57 too 0.64 W/kg, respectively. The Apple iPhone five has a caput SAR of 1.17 too a trunk SAR of 1.18 W/kg.
In the the United States of America no personal wireless device tin sack lead keep a SAR that exceeds 1.6 W/kg. The SAR standard, however, was developed several decades agone inward the the United States of America primarily past times physicists too engineers to protect users from the astute effects of the oestrus generated past times microwave radiation. The standards create non protect users from the non-thermal effects of jail cellphone telephone radiations which lead keep been associated amongst increased encephalon cancer adventure amid long-term jail cellphone telephone users too other wellness problems inward the curt term including electrosensitivity, sperm harm too infertility, too reproductive wellness risks inward children.
Just because these devices are legal does non hateful they are safe
Although many wellness researchers, including myself, lead keep questioned the utility of assessing alone a device's SAR, currently that is all governments mensurate too regulate.

Governments desire consumers to believe that all legally marketed wireless devices are safe, too that the SAR degree does non thing every bit long every bit it meets the legal standard. Yet no study has proved that exposure to low-intensity microwave radiations is safe, too thousands of peer-reviewed, published studies lead keep constitute biologic effects from such exposures. The inquiry suggests that governments remove to adopt to a greater extent than stringent, biologically-based, standards to protect consumers' health.
Medical too populace wellness professionals should telephone band on Google to halt this experiment on Glass users or at to the lowest degree fully inform consumers of the potential long-term wellness risks from wearing this device.

Google Glass SAR exam study update
Following are the results from the SAR exam study for the Google Glass Model GG1 (A4R-GG1; dated May 18, 2015):
Head test: 0.293 W/kg for Wi-Fi (2.4 GHz) too 0.790 W/kg for Wi-Fi (5 GHz)
Simultaneous transmission: 0.874 W/kg
Bluetooth was excluded from testing every bit the maximum output ability is 2.0 dBm.
