This is not a question of when the RX actually expires...

I'm new here and been in the business for about 10 years. When I first started it was told to me by another optician, that if the Rx is 3 months from expiration we can only sell them enough lenses to get them thru the end of the prescription. The logic being that it is a medical device and they need to be re-evaluated once that Rx expires. I was discussing this with a co-worker earlier and could not find any clear cut information online(prior to arriving on this site in the middle of the expiration debate thread).

Can someone walk in 3 months prior to expiration and order a year supply? My thinking is NO. We can't sell them a 2 year supply the day of their exam(provided the Rx is written for 1 year).

I'm hoping to get a more straightforward answer versus speculation and my "logic".

Thanks in advance!
