Can iPad LED screens cause retina damage?
Hello,
In this article from a Spanish research: http://www.thinkspain.com/news-spain/22749/led-lighting-damages-eyes-says-spanis h-investigator they describe some potential eye's retina damage caused by long exposition to blue LED light.
I find it a little uncomfortable about my two children using my iPad a lot of hours a day, but since the author of the study does not show any factual evidence, and has also conveniently developed a filter to attach to any portable device, I doubt the suspicious economical motivations of the research. Writing form Spain, I will not link to the site, since I don't want to appear as connected to this study either... but I am really worried, and so:
* How much blue LED lights do Apple devices emit?
* Is there any real danger, do the iPad screen's displays filter in any way these emissions?
* As intensity of light is pointed as a key factor of this potential damage, is there a way to block the contrast of my iPad, so that my child can't easily put it at maximum?
Please, I am very interested in your opinions.
