How to check if post has previous_comments_link() and next_comments_link()

I should probably do

<?php if( previous_comments_link() ) : ?>
  <li class="previous">
    <?php previous_comments_link( __( '&larr; Older Comments', '' ) ); ?>
  </li>
<?php endif; ?>

<?php if( next_comments_link() ) : ?>
  <li class="next">
    <?php next_comments_link( __( '&larr; Newer Comments', '' ) ); ?>
  </li>
<?php endif; ?>
