is it worth?

my eyes are so painful now..
facing in front of the laptop screen for too long..
started from two days ago..
i sat in front of the laptop and typed my thesis as early as 3am.. non-stop till 12 mid-night..
spent almost 18 hours each day in front of the laptop..
the end result is..
double vision..
swelling eyes..
painful..
redness..
bloating with blood vessels..

t.h.e.s.i.s.
is it worth???
