I work in the industry and am quite familiar with optics, various products and more importantly how they are all manufactured so feel free to PM me with any questions. The coatings aren`t just a pitch. It`s not so much about the anti scratch and Olieophobic or hydrophobic properties as it is about the reduction of glare from and back. Although the warranty that comes with most good coatings tends to be for 2-3 years thus well worth the cost. Blue light protection / reduction is also important and part of most good coatings as well.
Believe me, the difference with and without AR (Anti Reflective) is big. You`re mentioning 45yrs so you`re likely in need of reading zone magnification aka presbyopia. Welcome to the world of progressive lenses vs OTC readers
Again, happy to help.
For all those wondering, the difference between typical lower end lenses sold at Wally World and good high quality digital ones is like the difference between a Sears 10" polisher and a high end Rupes Long throw or a Flex 3401. Seriously.
