I'm back to riding and feeling stronger. I really

my regular eyewear. They have always been horrible.

You get the prescription (the slip of paper with info about what
correction you need) from your optometrist, obviously. There are several
ways you can get that prescription filled. You can give Performance the
info from that prescription and they'll have the lenses cut and
installed in the adapter. Or, you can get just the empty adapter, take
it and your prescription to your optometrist/optician, and they'll cut
and install the lenses for you.

Performance charges $50 to cut and install the prescription lenses, so
unless the lenses are covered by your insurance, that;s probably the
cheaper route.

The bigger issue for me, though, is that unless you wear contacts half
the time, I don't think double-lens systemsare particularly great,
whether they be clip-ons, over-glass goggles for skiing, or sunglasses
with an Rx adapter. They suffer from considerable glare, especially if
the sun's at your side, and they tend to fog between the lenses if it's
cold out.

I wear glasses full-time and I went to my optometrist, got a mid-level
pair of Bolles with full-lens frames (the frames wrap all the way around
the lens), and they popped out the regular lenses and replaced them with
my prescription. The frames are contoured to the face, and have better
peripheral vision than my regular glasses, and are great with both glare
and fog.

Like I say, unless you wear contacts a good portion of the time,
dedicated prescription sunglasses are a far better choice than a Rx
adapter.

Good luck!

You are saying which I kinda thought.

Which Bolles did you get?

I'm back to riding and feeling stronger. I really
think that I should get something better than
my regular eyewear. They have always been horrible.

If you need prescription glasses when riding, I'd try some clip-on
sunglasses first. If that's not satisfactory (and in my experience,
most clip-ons are awful, but your results may vary) then a pair of
prescription sunglasses is a good move...but I'd shop first at a place
that sells *glasses*. This is not without its potential for pitfalls.
The last time I shopped for glasses, I had to visit three stores
before I found one that was still stocking frames that carried a lens
of reasonable size. Itty-bitty frames are "fashionable" (a word I
have come to detest with a level of disgust previously reserved only
for evangelists and neo-con politicians), and many stores have no
frames that carry a useful size of lens. The upshot is that it's
sometimes difficult to get useful glasses made at all. As for buying
performance-oriented frames and having the lenses fitted at the local
optical lab, don't count on that being possible. You would be amazed
at the number of labs that now use a fitting system that is designed
to be goof-proof and user-friendly...and in part due to the lack of
training often given the operators of the machinery, can only be used
to fit a lens into a frame for which they have a stored template. Thy
*won't* have a template for frames bought elsewhere in most cases.
(On the other hand, a *good* lab can fit them...but good labs are
dwindling in number as the "we'll make your glasses in 17 minutes or
less" stores grab ever more of the market share.)

If you can find a supplier that will fill your prescription sunglass
order by mail, that's second best. There are still fitting issues
that may require adjustment of the lens centering which isn't noted on
the scrip, and the frames themselves may need adjustment as well.
That's not easily done at a distance.

Alternate solution: Get contacts and use regular sunglasses.
(Doesn't work for me; my prescription isn't strong enough, so I'm
stuck with regular glasses.)

Residents of California (and possibly elsewhere) may find this
exceptionally difficult to obtain. My ex used to drive from Palm
Springs to Las Vegas to get her glasses precisely because she couldn't
find an optometrist in her area who would just hand her the scrip, but
in Nevada there was no such problem.

Those optometrists are not in compliance with the law, which
specifically states that prescriptions are portable, which means that a
lens prescription must be furnished at the patient's request anytime up
to one year after the examination.

A simple call to the state agency which regulates optometrists will
confirm that, and they will be interested in knowing the name of the
practitioner who refused to do so.

I got the Zuma, which they no longer make, but you can get them NOS/NIB on
ebay for $40-$60. Among current models, they resemble most the Chill or the
Santa Marta.

Fogging can occur when you go through fog or go from one temperature to
another rapidly. Hot outside to cold inside. This morning my group
rode through some heavy fog off the river. My glasses were fogged up.
And the guy who wears regular eyeglasses, no adaptor setup like mine,
just regular single lens glasses, also had fog on his glasses. So
whether you use single lens or double lens like my adaptor, both will
fog.

In cold weather, your own breath is the main source of fog. When cycling or
skiing, your forward motion clears the moisture. With double-lens systems,
the moisture is trapped between the lenses without enough airflow to clear
the fog. Yes, if you're riding through a patch of especially moist air, any
lens will fog on the outside, but that's far less common than your own
exhalation being the culprit, and the space between the lenses is the
problem.

At least, that's been my experience.

I have a pair of Rudy Project Kerosene, with the Rx adapter. I ride in
temps down to about 30f, and up to around 90f. I haven't had any
fogging, that was extreme, or a real problem.

I was able to get the Rx done in a progressive lense, which makes it
easier to read the cyclocomputer and to do any roadside work. With my
single vision, it was a problem, fixing a flat.

The Rudy Projects are pricey, for a decent value, check out the Tifosi
sunglasses. The Zoom with Rx adapter.

Life is Good!

My mistake; it was contacts, and this was back around '95. The regs
may have changed since then. California's optometrists (or at least
the ones who were hiding behind the reg) didn't want anyone to be able
to get disposable contacts by mail.

There were, however, states where the optometrist was permitted to
dispense glasses without providing a scrip as of the last time I
checked. Texas is *not* among them. The alleged rationale for this
was that fitting the glasses was as important as the prescription,
which has only very limited validity in the cases in which it applies.
(I will note that the fashion trends which have put adjustable nose
pads out of production at times can make fitting dicey, but this is
not an excuse for the chicanery which unscrupulous optometrists have
used in promoting such regs.)

you take the nosepiece with the frames on it that fit behind the
wraparound lenses to whoever you get glasses from them, and they
make lenses to fit the "diopter" frames.

they don't slide much, the temples use a rubber that stay in
place. they don't fog. i can see fine to the sides, but
remember that the corrective lenses don't wrap like the outer
lenses.

i think the radials are a good buy, but that the old radials were
better than the current radial 2s. i could have done without the
"improvements" like the vent holes. my problem was that i lose
at least one pair of sunglssses a year.
