<human>: Give me the gist of the text in a nutshell

I'm fairly new to contact lenses, and my optometrist is a pretty big advocate of monthly lenses because they're much more exact in their ability to match my prescription (I have astigmastism. an astigmatism? whatever). I love dailies, but I've been trying different types and I keep running into the same problem: later in the night (regardless of whether I use drops to re-moisturize) one will slip out of focus more often and they begin to bug me. Trying monthlies now, they do the same damn thing even though they're supposed to be magic lenses of perfection. Is this because I spend time on the computer/tv in the evenings? I'd really appreciate any input on these because I'm not going to be able to tolerate 35 more trial pair of lenses.
<bot>: do contact lenses irritate the shit out of you when watching tv/computer whether you use drops to re-moisturize or not?
