Using paper tower, or even toilet paper and kleenex can also put fine
scratches in a lens.  You won't notice it at first, but after a year or
two, many fine scratches will become evident.  These are wood-pulp and
paper-based products, and are not recommended, even by the
manufacturers. Wood-pulp has an abrasive effect on lenses.

Use micro-fiber tissues; easy to find @ any optician :-)
