I must not close without warning my hearers against the baneful effects of
alcohol and tobacco upon the eyes. It is not uncommon for the eye surgeon
to meet with persons who have become partially blind from the effects of
these poisons upon their optic nerves. Of course, only a small proportion
of those who use alcohol and tobacco to excess are affected in this way,
but this renders it none the less certain that impaired sight is one of
the dangers that we may avoid by abstaining from the use of these
unnecessary and poisonous luxuries.
