Yellowing of the eye-lens could be an influence as well.

Becoming shortsighted can be countered for by glasses and need not have
influence at all; but not if it gets very bad of course.

One problem is that with more years of active observing, your experience
will grow, yielding you more meteors, potentially upsetting the statistics.

The main problem with getting older I have experienced, is not the quality
of the eyes, but the fact that you tire more easily and cannot take long
observing sessions that well anymore.
