This means that light comes the same in your eyes, isn't it?
And, I repeat, one thing is the ambient light, another thing is reading books with the rays pointed in the direction of the pupil...and for several hours a day  |
The visible light travels through a special light guide so that it will illuminate the screen, which involves some light scattering into the eye. The IR beams are not aimed through the light guide, they are just above it, parallel to the screen surface. The IR beams are NOT directed at your pupil. Check for palpable heat. You can't feel any, because the dose is so incredibly tiny.
I repeat, the amount you've spent worrying over this far eclipses any risk. Go relax and read. You're welcome.
Why you've posted this in the Kobo forum, when you have a Kindle and a Tolino, is quite beyond me.
