I'm facing the prospect of my first serious job interview. I've graduated recently and am looking for a job in engineering. While I'm not too worried about the interview questions, there's one minor thing of concern to me - I have an ailment called nystagmus which basically means my eyes move constantly without me feeling it. 

Now, all the sources say that eye-contact is important during the interview, but, for obvious reasons, I won't be able to hold it for more than a few seconds. How should I handle this situation? Would it be better to try and maintain eye-contact (which could be a challenge), or should I not care too much about it and hope the quality of my answers is enough?
