They don't NEED to be replaced. That's your interpretation, not what I said.

3 to 5 years is about what we see for most boro workers who want to "change up" to either a new filter or a different frame style. Sometimes it is because the existing filter is scratched up from normal wear and tear. Sometimes it is an upgrade to a darker filter because either their work has changed or new glass on the market is requiring them to work with a darker filter. When the silvered soft glass became widely available, we noticed a large number of soft glass workers changing from AUR-92 filters to AGW-203 filters because of the color flare from the silver in the glass.

It's got nothing to do with the frame itself, because under our warranty program if the frame breaks under normal usage, you get a new frame (or if that particular frame is no longer available, a new pair of spectacles).

It is similar to folks who wear prescription glasses for normal daily usage. Unless their prescription changes quickly, most people will get new glasses every two to three years.

We've been doing this since the early 1990's, and it is our experience that the average replacement period runs between 3 and 6 years. Your mileage may vary.
