I am receiving conflicting information regarding the best way to clean
coated (anti-glare) spectacles without damaging the coating.

Presumably the cotton? lens cleaner supplied by the optician is ok - but
if this is not available will a soft paper tissue or linen handkerchief
damage the coating?

I've used linen handkerchiefs for decades without any problems, but I carry
them only to clean glasses with. Occasionally, of a morning, the tail of the
shirt I am putting on will be used instead.
