Rain-X on glasses?

Post by grayso » Sat, 31 Mar 2007 03:27:49


oh, by the way, i also got my eyes lasered some 5 or 6 years ago, and
i *love* it.  no side-effects (other than minor dry eyes very
infrequently), and no loss of up-close vision (yet, i'm 35).  even if
i have to use reading glasses in the future, i don't mind that so
much.  basically, i'd rather rely on glasses for my sedentary
activities (reading, assembling things, etc) than to rely on them for
outdoor activities where i'm battling fogging, goggle compatibility
(for skiing), retention on my head (for windsurfing, whitewater
kayaking), etc.  and yes i do use sunglasses or goggles with uv
protection *and* (usually) a hat with a brim for just about any
outdoor activities.  but it's really nice to be able to just pull off
the glasses when i really need to (when they fog or whatever) rather
than being 100% reliant on 'em.  my vision was pretty bad.  -3.5
diopter i think.  couldn't read the big E anyway.  and now i'm 20-20
or darn close.  love it, and i highly recommend it for those who are
good candidates for the surgery and who enjoy snow and water sports.

Grayson:  Lots of people complain about how Rain-X windshields smear.
I suggest several things that will eliminate smearing and make you
happy with or without Rain-X.

1.  Start with a clean windshield, inside and out.  Soaps, windex and
normal glass cleaners leave a chemical film that actually causes water
to bead after it dries and attracts dirt.  Moreover, none of these
methods really gets the scum and gunk that clings to the micro
scratches and small pits present on most windshields.  I own a 91 Alfa
Romeo with a windshield that appears sand blasted.  The only thing
that worked to markedly clean the windshield is a product called
Invisiglass.  It's available in a spray can at typical autoparts
stores and worth every penny.  Several applications will remove just
about anything, including globs of tar.  Probably not good for the
environment, but neither is driving.  Clean the inside of your
windshield with as much vigor.  Even if you wipe it with cloths or
clean every once in a while, and don't smoke, the outgassing from the
interior plastics and adheasives(that new car smell) will deposit on
the inside of all glass and make it fog.  Just a little fog on the
inside has a great impact on overall clarity of vision.

2.  Replace the windshield wipers and clean them once a week, replace
every three months.

3.  Apply only a tiny amount of Rain-X and buff in very well.  As the
direction says, a little goes a long way.  Too much will cause
streaking and smearing.  Less is more.  It works only after drying
completely.

4.  Don't use Rain-X washer fluid as it dissolves the stuff you worked
so hard to apply.

Don't know how much Rain-X costs.  As for windshields, mine shattered last
April, and I've been too cheap to replace it.

I think the caveat is just a CYA by the manufacturer. I've used Rain-X
for over 20 years on glass and plastic prescription glasses. I don't
really like it on an auto windshield, but it's great for sailing. In
my experience, you can get about a half-day of sailing before you need
to reapply. IMHO, ammonia based cleaners are what you need to avoid
for any lens that has AR [anti-reflective] or some other coating. And
to avoid that exploding super-nova effect when sailing into the sun,
from scratched lenses, best way to clean any lens is under running
water and plain ol' soap...

No windshied?  In the immortal words of the late, great Inspector
Clouseau,  "Problem sol-ved."

Yeah, I do have a great big empty head.
