Through this film everything seemed very "pixelated". How should I describe, usually you can see the pixels at this great display with the naked eye can not see, but after the application of the film, it sparkles like fresh snow in the sun. This is particularly annoying when white background (eg in the browser), as it looks "pixel" in all colors. Of course, this perception is subjective, especially when you consider that it is extremely influenced by short-sightedness about normal vision to presbyopia (so here probably the different ratings).
Nevertheless, this effect is there, he will be times weaker or disturbing perceived, depending on prescription. Presumably he disappears only if the structures in the film, who are responsible for the reduction in reflection, smaller and finer, so that they are no longer perceived just as the pixel from the eye.
