In tha last 40 years I've only broken one pair when I sat on them (couldn't
find them til I sat down!), Some have worn out, with nosepieces falling off.

In the previous 20 years, with mainly glass lenses 3 pairs a year was good
going! The first plastic lenses didn't last, they never said they were
plastic 8-(


And are you not afraid of looking a little out of date after 20 years in
those specs:-)?

Personally I wear glasses to see, not as a fashion statement. How
anybody can wear and usefully see through the modern "fashion" of a
pair of letter boxes is beyond me.

I don't think much of he current narrow lenses, as deep as the legs are wide,
where's the peripheral vision to the sides? Also the previous fashion of
super large lenses, which with short sight are exceedingly thick and heavy.



My optician suggests I have my eyes tested every 24 months.

Mine every 12 months. but they forgot to remind me last time.

Same here, my main prescription hasn't changed significantly for the
last 30 years or so. I have just started wearing varifocals though as
age related lens hardening meant I could no longer focus closer than
about 18" with my glasses but without 'em focus goes by 6". A 12"
"dead band" is big enough to be a PITA.

Mine didn't change significantly for years, just the fine tuning, which was
often wrong. they did change once I was past 60.

The pair I am wearing atm are currently good up to about 12" (intermediate,
for computer monitor at 800mm). In the morning I'm struggling with them at
800mm, my reading specs are better. The variation over the day is a big
pain, but several older reading pairs fill the closer dead bands. My previous
pair of distance glasses were weaker, but are better for morning driving,
with my current pair being better in the evening.

Someone I know had laser surgery on his eyes about 20 years ago. the first
eye was fine but he had to give up driving, as the second job produced a view
as if through a very scratched windscreen. Fortunately a second skim in
Harley street at great expense was able to get rid of the scratches. I'd like
to hacve my myopia (and astigmatism corrected, but with a 'lazy' eye, I can't
risk the good one, until cataracts eventually mature enough to make it
irrelevant.

That seems to be true, I discussed it with the nice young lady conducting my
penultinmate eye test, as she used minus cylinder. She said it depended on
which instituion did the training. She had worked at a lab during university
vacations and had got very used to transctibing, and decided it was easier
using minus cylinder.


I assume the "Axis" starts at 3 oclock and increases in a clockwise
direction.

I think it starts at 12 o'clock. I would think it's clockwise, but is it
different for each eye? I keep meaning to ask.

And that "Add" is a correction for close work.

Yes, but there may also be an intermediate distance "add".

Yes. An acquaintance went for a routine eye check and the opthamologist
told him to see his doctor straight away. She'd seen signs of a brain
tumour which was present with no other symptoms, and this early diagnosis
allowed successful surgery.

You can make new nosepieces, I have found, from sections of flexible plastic
tubing, cut to shape and stitched on with dental floss, which is pretty well
indestructible. I think mine has now lasted longer than the original!

Just go back to the shop and ask for a new one.

Usually they will do this for free

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Matty F
saying something like:

Why do the
pros use Latin instead of Right Eye and Left Eye?

Because of the possibility of confusion - normally the convention is
from the patient's /subject's /driver's viewpoint, but who knows what
viewpoint has been used if a third party is reading it.
The hard and fast naming of a part does away with the possibility of
removing the wrong kidney, leg, eye, etc, - you'd think, anyway. Of
course, that doesn't totally avoid the chance of total cockup, as
happened here, when a surgeon removed a healthy kidney from a kid,
leaving him with the bust one. This was in spite of the mother and
somebody else spotting the error and mentioning it.

I've had a couple of cataract operations which have left me with
distance sight in one eye and short-sight in the other. Surprisingly, it
works very well and I don't normally wear glasses at all. I wear a pair
of prescription glasses for driving - you should use all the help you
can get.

I've the same operation in one eye and the surgeon asked me if I wanted a
lens to give sharp distance vision or an intermediate one making it easier
for closer stuff. Since I'm slightly myopic in the other eye I opted for the
former which means I can cope with most situations without glasses

I doubt very much if the shop is still there, and the screw hole that fixed
the original is worn out - hence the stitching. The plastic tube I used is
actually softer and more comfortable than the hard original anyway.

I don't see how having Latin for Left and Right could help in any way.
Except for having jargon so that clients just pay exorbitant fees
without question.

It's a common practice to write on the part concerned with a felt tip
pen. If this is not done, the patient should ask why not.
Some professionals seem to have no common sense.

I used to wear glasses for driving. Five years ago I had a detached

cataract operation I've found my distance vision better without glasses
even though the damaged eye alone has very poor vision at any distance.
There seems to be some cognitive process at work that extracts the good
patches from my damaged retina.

Most of what everyone sees is the result of the brain applying
continuous photoshop type processes to what are actually very
much worse images from the eyes than you perceive.

I actually also had a test 10 years ago but again the prescription hadn't
changed so I didn't bother getting new glasses. However I finally broke my
30 year old specs last year by falling asleep on them and a nose piece
snapped off the 20 year old ones this year hence the new test before getting
new specs just in case anything had changed. Since it hasn't I'm rather
wishing I hadn't broken the old specs.

They did give me a "puff test" for intra eyeball pressure though which I've
never had before. It was all fine until on one go on my left eye the machine
puffed about three times as hard as it had done before and I shot backwards
off the seat like a stabbed ferret with tears streaming out of my eye. The
girl doing the test thought this was quite hilarious as I stumbled around
the room trying to get my sight back.

You can still get mistakes. People have marked the wrong side or
whatever before now. which is why there should be multiple checks, as
sooner or later, no matter how good someone is they will make a mistake.

Depends on what you mean by big I guess, but /specsavers (as i happen to
have been there recently) certainly have 'aviator' styles ones and
others of similar lense size - about 55mm diamater.

I'm very pleased with my rimless pair. Lenses are as big as I could get,
which is slightly smaller than my old ones, but they sit closer to my
face so no gap problem. They also don't slip down, partly due to
weighing bugger all and also I think due to the springy arms (no hinges).

I see RDS sells similar through one of his sites. Not cheap, but working
well.

Those are all the same reasons I'm more pleased with my rimless ones
than any other pair I've had in thirty mumble years, plus the less
noticable "edge" of vision where the frame isn't IYSWIM.

The only downside was suffering a headache for a couple of days while my
brain learnt to "map out" the four dots where the arms and bridge
impinge on the lens.
