(There are probably exceptions, but actual glass Rx eyeglass lenses are essentially obsolete, at least in the US.)

Compared to 'optical glass', TRIVEX is probably the next best readily available thing in terms of clarity.

Over the past year since my last eye exam, I bought (at least) seven pairs of eyeglasses (as I said, it's my other hobby): Four have CR39 'Plastic' lenses, and three of them are TRIVEX.

Normally (at least around here), TRIVEX is touted for its low density/light weight, and therefore its applicability to 'thick' prescriptions.

Personally, I don't care how much Trivex weighs compared to CR39; Trivex is so much clearer, to my eyes, that unless they come up with something better, I will get TRIVEX from now on (even though I supposedly don't "need" it in my Rx).

Again, HTH

Murphy

But my pocket knives and eyeglasses do.

Frame: Barton Perreira 'Watusi' • Color: 'Sandalwood' • Lenses: Hoya 'MyStyle' • Knives: Spyderco 'Jess Horn' (L) and Spyderco Kiwi (R)

And what, pray tell, is the Sixgunning Significance of that revelation?

Well, let me tell you.

Optically, these are the best eyeglasses I've ever owned, bar none.

Lenses

These are progressive bifocals called "MyStyle" by Hoya.

I also have experience with other brands, including:
• Shamir Autograph II (I also have these in my current Rx)
• Kodak Unique (Ditto)
• Varilux Comfort (Just to complete the list; IMO, this is obsolete technology, plus I don't have them in my current Rx)

The Hoyas have all of these beat so badly, it isn't even funny. I kid you not.

I haven't gone shooting yet wearing them, but dry firing alone tells me they'll be great for it. Everywhere else (for example, at the computer), the Hoyas are superior.

I can hardly believe how well these lenses work.

Coating

All of the Rx lenses I have owned to-date, except the Hoyas, have had Crizal anti-scratch and anti-reflection coatings on both surfaces. That includes Rx sunglasses.

The Crizal coating usually performed OK as long as it didn't craze; I've had two pairs that did. Those were replaced under warranty, but let's just say it wasn't much fun.

The Hoya "Super Hi Vision EX3" (same page as the lenses) is much clearer to my eyes, and it's held up fine so far. I've only had them about a month, so they're still pretty new.

Frame

The frame has been discontinued by the manufacturer, but I got this one on eBay, and I've seen others there. Barton Perreira sunglasses and eyeglass frames aren't cheap, but they are very well made. (Just be careful of fakes in this brand, not only on eBay.)

The main thing is the LARGE SIZE of the frame.

As Glen can tell you (or as just about anybody else can − lol) − I have a really fat head. This frame accomodates that.

For reference, the lens window is 57 mm wide (spec) by about 40 mm high. I say "about" because I only have stainless steel rulers, and I won't get any of them close enough to split hairs (or my lenses − lol).

Summary

Combine LARGE lenses with the truly digital/free-form design of the Hoya 'MyStyle', and guess what?

Well, let's just say you should check them out and "see" for yourself.

I think they are fantastic.
