Switching from Polycarbonate to Trivex Rx sunglasses - good idea??

Good evening, new to the board and have the following question, Rx prescription eyeglass wearer has used 8 base wrapped polycarbonate polarized sunglasses (Bolle Boa) for the past 7 years, (OD/OS = -6.00, no astigmatism) with great success, except the prescription in the lenses is now too weak (can't find my darn golf ball! LOL).

In the process of ordering new Rx sunglasses, since the technology ("B-thin") has improved to accommodate the new prescription (OD/OS = -6.75, no astigmatism) with a similar style of sunglasses (Bolle Bounty).

Intend to keep the old sunglasses to do yard work in, etc., but order the new sunglasses for driving, sports, etc. Have read glowing reviews of the relatively new material "Trivex". Is this material actually that much better than polycarbonate from a visual standpoint? Would there be difficulty in switching between the two materials/glasses for different activities? I tend to think, 'if it ain't broke, don't fix it' (i.e., stick with poly's), but if the new material is truly that much better, it may be advantageous to use it. Appreciate any advice, thanks. :smile:

It's only better for off center gaze, lateral chromatic aberration in the periphery and he'll have no periphery with either with that type of fitment and lenticularization.

if you want to switch someone to trivex start with the +6 patients, -3cyl patients and patients sensitive enough to realize their optics is crap in a -6 wrap.

If this patient cared about optics or had any sensitivity to it he would have told you when you put him in a 12 backside curve with 20 degrees of wrap, find someone who will appreciate it.

What "Other Eyecare-Related Field" might that be Chase2001?

Regardless, I wouldn't make a large eight base wrap with that Rx unless it was for medical reasons, and even then, I could probably find a solution that would allow a flatter base curve.

Take an 8 base drillmount and put a 4 base lens in it for a great compromise.
We do it all the time.

If you are in some "other eyecare-related field", you should already know the answers to your questions. But you are probably a consumer, right?
