For most of us it is too cold to go out to the shop so let us discuss bifocals instead of
bush and obama.

I'm sitting in front of my computer using my new bifocals. Progressives.

A couple weeks ago I received my company paid for safety glasses, also progressive.

At work, they suck. I talked to one of the guys that fit glasses today and he mentioned
that they do make progressives that have the near vision part both on top and at bottom of
glasses.

Anyone have those? Any comments?

You made the mistake of getting the progessive type.

From your postings, you need the conservative type that only allow you
to see as far as the tip of your nose. ;)

LOL

Okay...now in all seriousness I too have the progessive type..and they
have a learning curve associated with them.

If you find yourself doing certain work a significant amount of time,
then you need a fixed prescription for that work.

Hi,
since I got progressive bifocals I have to measure just about
everything to know
what I have, I used to pick my drills from a drawer and was pretty
sure about every
1/10 mm. Now I sometimes use calipers to tell the difference even
between
10 and 12 mm diameter. Moving the head up and down to focus took
some
2 month to become natural, but being half blind for differences below
1mm
really sucks.
Seems I have to live with that no matter how many near vision parts
the
glasses have. It got better with my second bifocals, they are 100%
for
near vision but only say 70% for distance. Less difference in the
glass
and absolutely OK for the workshop, but still no way to see 1/10mm
difference without some reference near by.

I have one pair for work and one pair for computer work and close up stuff.
They both use the same 'scipt but the ones for close up have a much
larger "reading" or close up section on the lenses.
They both work well but the biggest problem I notice is that I have to
turn my head to determine straightness, since everything looks bowed at
the ends in my peripheral view.

Fair shot. Wish I could see as close as the tip of my nose. I'm very near sighted and

F-ing useless crap, IMHO. I might, MIGHT try regular bifocals at some

say, you put masking tape over 90 % of the lens so that you were peering
out of a little vertical slit. Anything off to the sides was distorted.

Mine were the regular close-up on bottom version. The top & bottom
version can be had, but would do nothing for my problems with the
useless things. Swapping glasses works fine by me.

Like someone else here, I have to have two pairs of glasses: I have trifocal
progressives and bifocal for computer and reading. *Any* glasses that
contain more than one prescription are going to be a compromise. I could not
work the computer with my trifocals - their purpose is mainly distance
correction with the ability to read something quickly if needed and see the
car console when necessary. However, for really close work I still take the
glasses off completely.

One issue you might want to look at is how the glasses are adjusted. I had
to go back to the optician several times until I got both pairs adjusted so
that they worked properly. And do not be fobbed off by a bimbo with two
weeks' training. Get someone who knows what they are doing.

Hey Wes...it was meant as a little joke...please take it as
such. ;))))

I too am very near sighted.

With this problem of glasses, there is unfortunately no easy solution
except youth...which I too am losing.

The best solution is to go with the lined bifocals so you know where
the division is.

Then get speciality glasses for close work, far work and something in
between.

What drives me NUTS is when I am upside down in some machine and have
the wrong type of glasses on.

You will find yourself with your nose millimeters from a spinning
chuck/shaft checking something out and then realize how close to
getting killed you are.

It sucks to get old sometimes...

I should emphasize that it is very easy to forget how dangerous it is
trying to see something up close...and getting a wire, a metal
particle, etc. in the eye...thus losing an eye.

I know of several people who were trying to sneak a peek without their
glasses...and now sport a glass eye.

Makes for a great party trick when you pop it out....

Yo!

* A few years ago a salesman at Lenscrafters talked me into trying a pair of *progressive bifocals. After a week I brought them back and got normal bifocals.

* The problem with *progressive bifocals is that you need to move your entire head to maintain focus. So if you are driving and need to look at the side view mirror you will have to turn your head in that direction. If you roll your eyes to the side you will get a rolling sensation.

* The clincher for me was when I was working at the computer and glanced out to my right at a book on the table. I had such a sensation of falling that I grabbed onto the table with both hands.

Ok, I have to chime in on this one since I have personal experience that
differs alot from what has been discussed here so far. And I have learned
alot from this group but have not posted much.

I have had progressive lenses for, ahem, since 1995 (you do the math). They
are made by Varilux and are true progressive (brand name Panamic). One
poster mentioned they had tri-focal "progressives". Those are not true
progressives. True progreesive have a seemless prescription ground that
varies from reading distance to far range focussing. Tri-focals have three
distinct lense prescriptions combined into one lense.

My experinece with the Varilux is that they took very little time to get
used to (less than one day) and that they do not lose their focus at the
edges of the lenses. I have very broad peripheral vison and do not experince
any distortion of straight lines. If I strat seeing curvature in what I know
is a straight line, it means my astigmatism has changed and I need to get
the prescription corrected. Fortunately, the astigmatism hasn't moved much
in the last 6 years or so.

Also, I work behind a computer screen over 8 hours a day and at home another
3 or 4. I do not have a separate pair of reading glasses or what are
referred to in the trade as VDTs (video display terminal) glasses. I do not
like switching glasses to compensate for varying conditions. Having said
that, I am *very* picky about sharp focussing on the near distance (20") and
far distances (freeway signs). What I have found important to accomplish
this with progressive bifocals, is to make sure the short distance part of
the grind goes up high enough in the lense so that you do not have to "lift"
your head to read. Alot of dispensing opticians don't get this right. If you
have metal frame glasses, this can be compensated for sometimes by tweeking
the nose pieces to raise the level of the lense with respect to the center
of the eye.

I will agree with the poster that needed to focus when lying sideways while
wiring panels. I don't know of any lense that can compensate for that,
except a single vision lense ground for a specific distance.

And speaking of grinding, it makes all the difference in the world to the
quality of the lense. Optical labs must be certified to grind Varilux lense
blanks. Not just any optical lab can do it. And if the lab screws them up,
it is their dime to re-do them. These lenses are not cheap, so if they are
not right, complain until they make them right.

Oh, I don't work for Varilux or anyone else that can make money off of them.
I'm just a very satisfied user who is very picky when it comes to having
sharp vision. I do work for a vision care related company (that has no
interest in whether the customer chooses Varilux or any other lense maker)
and have some knowledge of lenses. But it is not what I do for them. I
architect computer systems to provide useful tools to other parts of the
company.

Hope this helps a few.

Thanks for the info, Mark. I'll look into Varilux.

I got progressives a bunch of years ago, and have been very pleased with
them. My optician spent quite a while determining what I do, and where my
eyes actually are. The result was glasses that took a matter of a few hours
to get used to.

The last time I got new lenses, I tried to cheap out on them, and that was a
big mistake. I never did get used to them; different progression in the
lenses, which for some reason cut the cost of the lenses by about a third.
I had a two-week "probation" for them, and ended up with the more expensive
lenses when all was said and done.

I tried real hard to like the progressives or gradient jobs, couldn't
get there. A particularly annoying aspect was reading: it was like
watching a pingpong match because the region of good focus was so
small I had to keep moving my head.

I get larger-than-usual (35mm) regions for closeup in my bifos. I
have had single-focus dedicated-purpose cheap specs made as for 'puter
use but haven't done that lately. The regular bifos seem to suffice
now.

Workin' under a dashboard? Fuggedaboudit! There are some things I am
too old to do, ain't that just a bleedin' bitch and oh pore me. G
A trick that might work if one really must work in confined space is
to tape a pinhole aperture on one's specs and have very good light.
There's actually a commercial product like that, with a little suction
cup. It's used in handgun bullseye shooting, helps presbyopic
oldfarts to better see both front sight and target.

Pricey. A bit of foil punched with a needle and held on with tape
works every bit as well.

In the good old days I could see clearly from my nose to outstretched
hand, period. Now (60+) the sharp focus range has moved out a little,
good for reading and computers but not much else.

What works for these eyes is safety glasses with magnifying patches in
the bottom, plus a 1.5X OptiVisor that serves as the upper trifocal
and helps block flying chips. My bifocals are OK for driving and
walking, useless up close, so I have safety glasses at each machine
and a soap holder on the wall to store the eyeglasses safely.

Your not wrong there Harold -along with getting grumpy and
conservative, eyesight (or lack of it) is a pain. As George Bernard
Shaw said.."Youth is wasted on the young"

progressive lenses - work OK for me, never had any problems. Fine for
reading, as the focal length is set up for that. Very little
pincushion distortion, but its wise to use a level when trying to set
something out. Driving is fine - I was taught to move my head and LOOK
around because of blind spots in mirrors.... For machining, not so
good - have to manually find the focal length to read verniers and
micrometers. (BTW - invested in a pair of non-digital verniers, got
the ****s with the batteries going flat all the time)

The real mongrel is SMD components in electronics - incredibly small,
if you drop one, forget about ever finding it. Use a magnifying lamp
to see them, but then loose depth perception.

So folks, we are stuffed. Rat cunning and experience are of no use,
sometimes...

And its coming up to our summer, 30 degrees C is a mild day. Drought
is in its 8th year, garden looks like its been blow torched. Try to
work, sweat drips into your eyes. Not good. At least we don't have to
worry about snow blower maintenance. And perhaps some of you guys can
tell me - every time I been in the snow, my feet get frozen - the rest
is ok, but the feet are almost painful. Wear 2 pairs of socks, good
leather work boots. Whats the secret, except for looking like some
idiot Snow Bunny...

And Merry Christmas to you all, thank you for the knowledge you have
gracefully given, and the entertainment in arguing politics etc. Our
family version of the Red Army descends on us Xmas Day, bloody hard
work and not much peace and goodwill. Hope you guys fare better.

A couple weeks ago I received my company paid for safety glasses, also
progressive.

At work, they suck. I talked to one of the guys that fit glasses today
and he mentioned
that they do make progressives that have the near vision part both on top
and at bottom of
glasses.

Anyone have those? Any comments?

Wes

I hate my bifocals. What I do now is to go to the dollar store and buy
cheap reading glasses in different powers. Depending on the task at hand I
will put these over the regular glasses to give me the focal distance I
want.

I was looking at those magnetic clip on sunglasses and I was thinking that
if I had different lenses put in the clip on part, that would allow me to
select just the right focal distance.

About the time I had mastered getting the toothpaste back in the tube, then
they come up with this striped stuff.

I have to vote with the guys who are pleased with their progressive
lenses. I have been wearing Varilux lenses since they came out.
The deal is, if you haven't already gotten this burned into your
gray matter by now, you have to pick a good optical company to work with
and you have to tell them exactly what you want and then keep coming
back until you get it.
As said previously, people like us have to get the "close up" area
to be high enough for our work. They tell me that many optometrists
still fit glasses for "reading" by fitting them for reading a book that
is held in you hands. That means that you'd be looking downwards to see
it. You'd hope that, by now, that industry would have realized that
computers don't ALL sit in your lap. So, you have to be real clear
about what you want to see and WHERE it is.
Bring samples of what you need to see with you to the office visit to
make sure YOU are getting what you want. The JC Whitney catalog is a
good one for me.


If you think the problems others have described so far are an issue,
have you tried electric welding with bifocals or progressives?
Especially with the small window in the basic helmets?

Also, note that we need LOTS more light as we age in order to get the
contrast we need to see well. At our lab, they figured 10X as much!

I know you probably dont's want to hear this, but those visor type
magnifiers might be a useful option now.

They are heavy, but they grip ice/slippery pretty well and
are the warmest boots I've ever had. Hold up pretty well
too. I've been wearing them for over 15 years now. Trudged 6
miles with them on so far today, probably do another 4 miles
later this afternoon. Altogether I average 10 miles a day
walking. Haven't been able to wear anything else now for the
past several weeks...

Just make sure you get the real thing and not one of the

No offense taken. I've been on usenet a long time under a number of aliases. I don't have
a thin skin.

I too am very near sighted.

The difference between eyes is the biggest problem. Reading glasses just don't work. At
least I can see really close up by lifting.

With this problem of glasses, there is unfortunately no easy solution
except youth...which I too am losing.

I know that feeling well.

The best solution is to go with the lined bifocals so you know where
the division is.

I'll get my next set of company paid glasses with the lines for reference. Be about 11
1/2 months for those.

Then get speciality glasses for close work, far work and something in
between.

I have a feeling i'll be ponying up bucks for glasses for the difficult situations.

What drives me NUTS is when I am upside down in some machine and have
the wrong type of glasses on.

You will find yourself with your nose millimeters from a spinning
chuck/shaft checking something out and then realize how close to
getting killed you are.

You must be way more nearsighted than me. 8" is my left eye. Right worse.


It sucks to get old sometimes...

Beats the alternative. As another said, every day you play golf above the grass is a good
day.

Merry Christmas and a Happy New Year,

My dad had GI issue boots like those. Sure were warm. Sadly, I grew up a bit more and
they didn't fit anymore. Same thing for mom's ice skates.

Thanks for the info, Mark. I'll look into Varilux.

Not sure who made mine. I had them made in photogrey.

Pricey. A bit of foil punched with a needle and held on with tape
works every bit as well.

I've been meaning to get one of those. My iron sighted rifles tend to have aperture

progressive lenses - work OK for me, never had any problems. Fine for
reading, as the focal length is set up for that. Very little
pincushion distortion, but its wise to use a level when trying to set
something out.

Never tried them, and I think that I never will.

Driving is fine - I was taught to move my head and LOOK
around because of blind spots in mirrors.... For machining, not so
good - have to manually find the focal length to read verniers and
micrometers. (BTW - invested in a pair of non-digital verniers, got
the ****s with the batteries going flat all the time)

It depends. Mitutoyo calipers seem to have pretty good battery
life -- about a year IIRC

Starrett ones go flat in a few months if just put away, but they
have the two large coin cells in a sliding holder. Slide it just about
1/8" and the batteries are disconnected from the circuitry so the
batteries go back to shelf life expectancy. Of course -- you have to
re-zero the calipers when you slide the batteries back into contact --
but it is easy, and makes for long battery life, so I'll stick with
that.

The cheap import ones (e.g. the ones which I got for about
$18.00 at a hamfest) go flat in three to six months with *good* cells
(the SR-357 ones). With cheap ones they last perhaps one month or two.
(The main question on those right now is "Where are they?" They're
supposed to be up here for convenience, while the other two are in the
shop near different machines.

And I do have one other very nice digital calipers, which I can
no longer use. These were B&S brand, and had an optical glass encoder
at the bottom of the groove where the rack gear would be on dial
calipers -- *but* they require PX-13 cells -- Mercury cells which are
now made of unobtanium (at least here in the Politcally Correct USA).
(And the B&S did tend to drain the cells fairly quickly for the price --
about six months IIRC.)

But -- I got several years of use out of a $15.00 purchase at a
hamfest -- supplied in fitted wooden box -- before the cells became
unavailable.

The real mongrel is SMD components in electronics - incredibly small,
if you drop one, forget about ever finding it. Use a magnifying lamp
to see them, but then loose depth perception.

Stereo Zoom microscope for the depth perception -- but perhaps
the magnifying lamp to *find* it first. :-)

So folks, we are stuffed. Rat cunning and experience are of no use,
sometimes...

And its coming up to our summer, 30 degrees C is a mild day.

Hmm ... it'a about 30 here at the moment -- but that is 30 F,
which is just a bit below 0 C. :-)

Drought
is in its 8th year, garden looks like its been blow torched. Try to
work, sweat drips into your eyes. Not good. At least we don't have to
worry about snow blower maintenance. And perhaps some of you guys can
tell me - every time I been in the snow, my feet get frozen - the rest
is ok, but the feet are almost painful. Wear 2 pairs of socks, good
leather work boots. Whats the secret, except for looking like some
idiot Snow Bunny...

*Good* work boots with insulated soles, and don't stand in the
with it contacting the sides of the uppers for any duration. Stomp down
a flat area, and keep the feet in the middle of that. :-) My work boots
are supposedly insulated thermally, electrically, and good for non-slip
in oil.

And Merry Christmas to you all, thank you for the knowledge you have
gracefully given,

And the same to you,

My beloved got nice and medium dark ones. She has Hazel eyes.
I on the other hand that used to wear #3 dark lenses overseas got a pair
that on a good day you can see a tinge of color. Almost useless for
sun glasses. Bad for blue eyes that are more sensitive.

I'm also extremely near-sighted, and wear contact lenses. As my
lenses have hardened in recent years, I've now got:

-reading glasses. Constant-correction.

-reading half-glasses. Constant correction, but the lenses are small
enough I can see over them at more-distant things. They also have a
metal tube and fit nicely in my pants pocket.

-reading safety glasses. Constant-correction. These are the only
ones that cost some significant money, since I couldn't find
constant-correction safety glasses (only bifocals) except by
prescription.

My eyes are still good enough that switching from CRT to LCD has let
me put my monitor far enough back on my desk that I can read it
without the reading glasses (which also gives me a *lot* more desk
space).

People with old film cameras, lightmeters, et al, all used mercury cells
and so have the same problem.

One standard fix is a silver oxide battery cell with a forward-biased
germanium diode in series (to drop the voltage to ~1.35 volts). A
digital caliper is probably tolerant of voltage, and may well be happy
with silver oxide and no diode.

Fair shot. Wish I could see as close as the tip of my nose. I'm very near
sighted and
miss my very close up vision. Have to take my glases off to see really
near and that is
only one eye. My distance vison is -2.25 and -4.5 iirc. I lost the overlap
as I got
older.



Okay...now in all seriousness I too have the progessive type..and they
have a learning curve associated with them.

I'm working on it. My head keeps bob bob bobing away. I'm sure your
recognize the 78 rpm
record that came from.



If you find yourself doing certain work a significant amount of time,
then you need a fixed prescription for that work.

I have a feeling I'm going to need to look into that. Working on one's
side laying on the
floor rewiring a panel sucks with what I have currently. Same for doing
machining if I
need to make a detail to repair something.

Wes

I should emphasize that it is very easy to forget how dangerous it is
trying to see something up close...and getting a wire, a metal
particle, etc. in the eye...thus losing an eye.

I know of several people who were trying to sneak a peek without their
glasses...and now sport a glass eye.

Makes for a great party trick when you pop it out....

TMT


They DO make glasses with the greater magnification (shorter focal length)
at the top, for guys who like to hang ceilings and stuff. Great for being
under the dashboard, inside machines and so on - and don't ask me if turning
mine over for that was a practical idea. Complications ensuing from THAT
maneuver was what made have to go buy a new pair. Again!
