Mangekyo Sharingan. I remember when I got Lasik'ed a couple years ago, they told me that young folk like myself (especially those who used computers a lot) ran the distinct risk of probably having to get it done again in like 10 years or so. And despite the side effect of kinda jacking up my night vision, I don't regret having it done at all- it's SO convenient compared to the glasses and contacts. People blessed with perfect eyesight, live it up- you don't know how good you have it.

Well, anyways, maybe a month or two after I started working, I started getting these terrible headaches. After awhile, I realized that it was (probably) cuz the vision in my left eye was noticeably worse than in my right. And I think the imbalance in clarity was causing the dizziness/aching. I talked to my coworker about it and he was like, "yea, that happened to me too when I first started working. I used to have perfect vision all my life until then, and I went to the optometrist and she was like, 'I bet you're an engineer, fresh out of school, huh?' And I was like, 'how did you know??' 'I see it all the time. You start this job where you're staring at a computer screen for 8+ hours a day, and your eyes aren't used to it.' So yea, that's common; it's like beginning engineer's disease." >_< And it reminded me of that line in Naruto where Kakashi says to Itachi (about the mangekyo sharingan): "[how far has your eyesight deteriorated, Itachi?]" But whereas mangekyo sharingan is an ultimate bloodline genjutsu technique capable of completely incapacitating an opponent in a split second... well, it seems I've traded my eyesight for, ummm... heat transfer and finite element analysis techniques. >_< Yea, I wish I'd gained something cooler for sacrificing my vision. -_- *le sigh* I dunno, I'd sooner get Lasik done again than go back to contacts, but... we'll see, hopefully I can tough it out and make these eyes last a bit longer.
