polarized vs nonpolarized sunglasses

Mike said:

Hi, I'm checking around for new sunglasses, maybe Oakley M Frames.
Wondering if it is worth the extra bucks to go polarized or not. Any
comments?

It's definitely easier to see motorists flip you off through the
window glare with polarized lenses.

No. polarized is for glare on a windshield, or for fisherman who stare at
the water all day, boaters, etc. I have worn polarized on a bike, and I
didn't like it.

They're good for cutting glare on the water for boaters and fishermen, but
even then I'm not sold on them -- they make my eyes tired compared to
regular lenses. I have no idea why. Most other sailors I know have this
same complaint.

On the road they cut glare too but this is not always a good thing. It
can make it hard to distinguish between damp, wet, and slippery surfaces.

And depending on the orientation of the LCD, they can make it
impossible to read your computer.

Exactly. LCDs comprise of two polarized layers and the orientation of
the number segments changes when current flows through them. This
results in a darkened segment as light cannot pass through a
perpendicular cross orientation. When wearing Polaroid sunglasses, the
whole screen will become darkened if the orientation is normal to the
layers in the LCD.

....or LCD instruments, or even your LCD watch.

Everyone's different, but I love polarized when I kayak. It's the only way,
to see what's under the surface. They do not tire me at all. On a bike,
they put me to sleep, what gives? I see no advantages, on a bike, but see
lots of disadvantages.

You know they're selling those "transition lenses" that darken with the sun.
Someone told me they don't work when driving a car because the windshield
has a uv blocker, and without the UV, hitting the lens they don't darken.
So much for transitions.

try http://www.yorktowneoptical.com/Instant.html
the shades carry wings at the temple sides that emilinate reflection
from the rear and above: vey comfortable.
notice the polarized shades: these are the most effective as in blue
glare guard for bright sun, copper for less sun or cloudy, the
polarization increases depth perception. Copper is spectacular with
sky blue/cloud white.
the yellow may be worn at twilight or at night to eliminate oncoming
auto headlamp glare. if polarized shades blind you to LCD then you
should see a doctor or two doctors.

I don't know that it's the UV blocking effect of the windshield, as
much as it is that you are sheltered from most direct sunlight.
Transistions seem to darken just fine laying on top of the dash.
Results may vary with newer windshields that have UV blocking
built-in.

But, since this is r.b.t and not r.auto.tech, I think transitions are
a plus as they allow the rider to have dark (sun) glasses and the
needed prescription effects.

You do not understand the interaction between polarized
eye-glass lenses and a LCD display. Look up the physics
of LCD displays.

The advantage of polarized on the road is that it cuts out sun glare
off car windows and polished bodies. It also cuts out sun glare from
the road surface, but that's a matter of taste.

I saw that everyone else has an opinion soo....
Mine are polarized UV blockers that I put (Mickey Mouse) window tint
film on to get really dark. For your question, they tend to block mostly
the refection of light from car windows, bumpers and other blinding
events, but also mask water on the road, and make it easier to see fish
in the water.
I like them, except for the puddle problem, but I try to only bike in
dry weather, which California is good for.
In the midwest you can get hit by a 5 minute 'ambush' thunderstorm.
Maybe two sets, depending on conditions.

Sometimes that flash off of car window let's you see cars that are way out
there. It's like night riding, when you see the headlights way before you
hear them. But like you said, it's a matter of taste.

some I can see, some I can't with polarized. Don't have a clue why, but I
would say polarized interferes with seeing the computer numbers.

That may be true. I do have to remove my sunglasses to read the
computer, but mine is a $10 China-Schwinn.
My suspicion is just the crummy contrast on the Schwinn.
Bill Baka

well, i use polarized, cateye, and timex and have noooo idea of not
seeing the numbers.
on UV, yawl better google UV and UV protection soas to get up to speed
onit.
whithout looking, i remember glass and carbonate ('unbreakable
lenses'😉 reflect UV?
what that means to mountain climbing glasses that claim... ?
there's a lotta snake oil in there somewhere.
try serengeti-eyewear.com for polycarbonate photochromatic if ur
looking to spend $$$

I'm not a fan of eyewear that essentially changes transparency as you change
your angle to the sun... in other words, as you go through a corner, the
actual light may remain constant, but what you perceive may be quite
different, at times causing things to be darker than you might like (with
your eyes not adjusting quickly enough).

Newer generations of polarized eyewear are different though; the Oakleys
have a fairly light amount of polarization effect vs their normal tint, so
you don't get quite such a dramatic change.

No, actually it can be harder to see them, depending on the car. Some
GM minivan windshields are nearly opaque to me with polarized lenses.
Glass that is stressed while being made tends to develop some odd
polarization that can interfere with the polarized glasses. From the
inside the effect is less noticable, so driving with the m on is not a
problem.

BTW, I really like my polarized lenses for riding. It can even be an
advantage to not see that guy flip you off, but the big thing is the
general reduction in glare.

Others (like Jobst) disagree, saying that it is harder to see water or
ice (which?) on the road, but I have not experienced that, and have been
using polarized sunglasses for several years.

The only downside is the occasional window or cyclocomputer screen that
is accidentally polarized. Well, actually all lcd screens are
polarized, but good ones are still visible with polarized glasses, since
the polarization is on the same axis. Turn your head sideways and the
screen is unreadable. I buy cyclocomputers while wearing my glasses
just to be sure.
