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?

Microfibre cloths are considered best, tissues are OK.
Hankies as long as they are clean and free from dust/grit are fine.
The vast majority of spectacle coatings are anti scratch as well as anti
reflection so unless you are wiping them with something obviously gritty or
potentially dirty you should be OK.
