High index/Aspheric causing narrow sharp field of vision?

Hi,

I got my new glasses two weeks ago and I have a some problems with
them.

The glasses and my prescription are:
Silhouette Titan Minimal
Essilor Stylis, index 1.67, aspheric.
Left: -4.25, 0.0 astigmatism
Right: -4.25, 0.25 astigmatism

I get a VERY narrow sharp field of vision, I estimate about 15 degrees
to the left and 15 degrees to the right, total 30 degrees when I check
with one eye open.
About the same when I tilt my head up and down, where I also have to
tilt it up a bit to be able to see sharp straight ahead.

I have had headaches every day since I first got the glasses, perhaps
more on the left side of my head.

No fitting was done before ordering and no pupillar measurements were
taken.

Because I hade done some reading in this forum I specifically asked
for the edges not to be polished, but they were polished when I got
them. This is very annoying since the reflections are very disturbing
especially on a bright day when I frequently get blinded by the
reflections off the bottom of the lenses.

My old glasses had glass lenses of high index (I don't know exactly
what index) and I experienced quite obvious chromatic abberation with
them periferally, but they gave me a wider sharp field of vision.
The new lenses have less chromatic abberation but a much narrower
sharp field of vision, it's kind of hard to tell about the chromatic
abberation since it is quite blurry instead.

The first time I went back and complained my optician just told me to
wear them for two weeks and come back if it didn't feel better.
Today when I went to see her she almost immediately offered to take
the glasses back and have them refitted with non-aspherical lenses of
the same brand and material.

The problem I have is that after reading some topics in this forum I
am not quite convinced that it will help me by just getting
non-asperical lenses.

Would it be better to use lenses of some other index and material?
And should I get the edges polished or not? Maybe have AR coating put
on them, can that be done on Essilor Stylis lenses?
I am quite sensitive when it comes to vision but I don't want my
glasses to be too thick.

I almost stopped reading your post right here. That alone is enough to
bring them back and make a quick exit.

Seems like the optician doesn't have it together. Let's see how many
more mistakes can be made for one order........

Did she recommend Tylenol and Valium, too?

Nice to see that you learn stuff here!

AR is not the answer. I'd suggest using a lower high index lens that
has a decent Abbe value, keeping the lens thinner and lighter and
providing better optics. At a different optician who first fits the
frame, measures your PD, sets the vertical optical center height and
communicates clearly with you. I dont have my lens reference guide in
front of me, so I can't offer you specific brands/designs. Perhaps one
the forums knowledgable opticians will reply to your posts.

Sorry for initially sounding flippant, but it bothers me when someone
with justified complaints is dismissed out of hand like that.

In my limited personal experience, I'm a big fan of the week or two
thing. I first got glasses in the fourth grade, and I remember it took a
few days to get used to them. Back in those days, small lenses were
popular. I wore that style of glasses for decades. When my eyes
stabilized, I wore the same pair of glasses for many years. Back when big
lenses were the style, I tried wearing a pair. I just couldn't get used
to them. I tried for about two weeks, off and on, and it always felt so
good to put my old glasses back on that I just gave up on the new ones. A
couple of years later, I got some new glasses, much bigger than my old
ones, but much smaller than the ones that didn't work. After a few weeks,
I though I'd try on the glasses that didn't work and see how they felt.
They worked fine! My theory is that my brain just couldn't get used to
the difference between the small lenses and the big ones (and they were
rectangular, which made the corners pretty thick), but could get used to
them if I could transition from small to medium to large.

 

I can't tolerate aspheric lenses -- the edges are unbearably blurry. It
was as simple as that for me, and I'm both very myopic and very exacting
about my vision. I'm doing fine with Hoya 1.71 index. They were
much thinner than Vizio 1.66 atorics in the same frame and prescription,
and most importantly I can SEE out of them. Very careful measurements
were taken before the lenses were made; those same measurements were
used to make the replacement lenses. Night and day.

By the way, I get a slight edge roll but NOT a polish, and I like the
result. I don't think it adds much to the 'coke bottle effect' at all,
and the edges aren't shiny so they don't distract me OR call attention
to their thickness. YMMV depending on the frames and lenses and
prescription and phase of the moon.
