Please share why coatings are important.
I've done a lot of photography over the years, and even went through a six week intensive 8-hour per day DoD photography school many many years ago. I just had my eyes examined by a long time friend. Nothing is like it was even a few years ago. Consequently, I don't feel comfortable answering that question.
I'd rather refer you to the latest info from
Wiki-pedia In any case, coatings do make a a big difference in light thru-put, glare, scratch resistance, and many other factors.
