I have an anti-reflective coating on my polycarbonate lens bifocal glasses (yes, I am "older") because I look at a computer screen all day (well, not any more). That is another consideration to make when an eyeglass place makes a suggestion to have your lens coated IF you stare at a computer screen all day in your line of work (like me as a (former) CAD Engineering Technician; AKA, draftsmen).
One caveat to coated lens is that the coating scratches easily, so beware of how you clean your lens. DO NOT use your polyester moisture-wicking shirt and breath moisture after cutting the lawn to clean coated lens. There are specific lens-cleaning microfiber clothes and cleaning sprays (which work wonders as well on computer touch screens).
Another caveat is your skin complexion and body acidity. If you have an oily skin complexion and it is acidic, it will eat (actually etch) certain coatings that come in contact with your face skin over the years that you wear the glasses. Just be aware of that. Most places have a one-year one-time warranty on coatings. I was told by the eye glass technician to use the warranty automatically before the first year was up in my situation so I would get at least 2 years of good use out of coated lens. The eye place I used said they can strip and recoat a lens, but you pay for it once it is out of warranty.
