Polycarbonate lenses

[Uilleann]

Sounds like your chosen supplier has a real problem with availability and pricing. Might want to look for a new one.

Given that Nassau is a large national supplier, I'm certainly not the only lab to be seeing the same. As far as other sources, even surfaced Trivex lenses are routinely on backorder at the 3 other wholesale labs we work with. So definitely a material issue globally.

our lab uses almost exclusively trivex at my office w/ no delay, takes maybe 2 weeks at most from beginning to end

85+% trivex here. I literally can't remember the last back order.

And this is stock lenses? Why are they taking 2 weeks? I have every other material in 98% of cases in hand in 1-2 days. It's only Trivex that's rare and expensive. While less so through our regular wholesale lab when surfacing lenses, as a percentage of backorders goes, Trivex also leads. *shrug*

only our sv, but we do probably 90% free form PAL's, the rest usually have transitions or AR or both, our stock lenses with shipping take 3-4ish days depending on the post office

One of the opticians here ordered a progressive lens in trivex from Hoya with a blue light filter and EX4 as uncuts, they said its on an indefinite backorder. 16 days later they said the backorder is still ongoing and they could switch it to poly if we wanted. I asked them to switch it to Recharge and keep it in trivex.

Since Uilleann mentioned my country (Malaysia), seemed fun enough to reply, why not... :P

We don't seem to have a backorder of Trivex in Southeast Asia in general (and yes, I'm in friendly communications with some colleagues in neighbouring districts or even countries in the region). No plants in Malaysia produce lens blanks AFAIK, if anything the blanks are more likely to be imported via Thailand, maybe China. However, that said, most stock Trivex here (usually just clear lenses without any added on blue cut function) takes up to maybe a week, and ground Trivex lenses (clear, photochromic, or tinted as available according to lab) usually up to three weeks. Quite often the wait is attributed to shipping delays as opposed to supply issues.

Trivex/Tribrid just never did catch on hugely here (mostly due to cost, I suppose), in fact neither did polycarbonate (to a lesser extent). While polycarbonate is reasonably common here especially for paediatrics, 1.60 remains preferred in many cases for local dispensing. This due to polycarbonate lenses here seemingly having poor coating scratch resistance despite the intrinsic impact resistance.

All of the above with respect to both finished stock lenses and also custom ground lenses.
