I never do till they are teenagers. I used to not recommend it because AR was hard to keep clean and scratched easily.

Now with the better ARs they are very scratch resistant and are easier to clean so I am wondering if it is something I should start talking about for kid's eyewear. I hesitant because most kids are terrrible about cleaning their glasses and AR lenses do have to be cleaned often.

I notice that Walmart sells it to kids now. The few I have seen usually look terrible.

What do you do and why?
