Hrm. I can see metal perfectly fine with one eye closed....

Maybe there's another description?

That's fascinating, but now I'd like to see it and I can't which is
frustrating.

For you, metal looks "shiny," yes. But "metallic" is something slightly
different. Because the eyes are separated by 65 mm or so, each eye gets a
slightly different look at surfaces. This makes no difference for
flat-textured objects and colors, but shiny surfaces never reflect light
exactly the same for each eye. The difference in relative intensity gives
finished metal a special "look" that goes away when two-eyed people close
one eye.

The same "metallic" phenomenon is used by color-blind people wearing the
X-chrom lens. The X-chrom is a patented deep red contact lens worn in one
eye only. It filters everything but red light, so red objects are seen
roughly the same intensity in each eye. Green objects are much dimmer in the
eye wearing the contact, but still bright in the non-wearing eye. The
difference in intensity creates a "metallic" appearance that helps
distinguish red from green. They don't "see" colors, but they distinguish
between them better. Green objects look "metallic."

Well that's interesting. I've only got one eye and I can't say that
I've noticed metal things not looking metallic..

Within a few hours for me. But my pair of long sighted glasses do help
slightly actually within that time period. I was just curious. I always
took it for normal, but no one ever said what normal was. Now it is
normal I shall ignore it.

Thanks for your time.

Absolutely, yes, all this would follow as a consequence of the cycloplegic
drops.

The trouble should all be gone by the next day.

There's only three things that's different for me since this came about...

1) I picked up a first pair of test specs for long sightedness (Im only
tlaking about +1.25 in each eye IIRC), I've hardly worn them to be
honest, only when I've had bad eye strain, and a second eye test, six
months after being told my hyperopia had increased, consider getting a
pair of glasses if there's a problem, six months after that my hyperopia
was back down and apparently I was better than before! Which I can only
put down to...
2) I am now on 150 mcg of Thyroxine... TSH is 0.5 and T4 is 16.1. I have
an underactive thyroid.
3) Apparently I've been on Lansoprazole since September.

I'll keep you filled in on any progress.

I love this newsgroup.

Just got to look up all those words now.

I don't know. No one has told me yet.

Hrm. Fusion breaking? Hrm. I know they performed a Bagolini test, white
dot, white lines, and ran a bar of prisms up... dunno if that's the same
thing, but they ran up about 4 or 5 segments before the lines split.

No one's ever told me my phoria. From what the consultant has told me,
it is apparently minor. I suppose now might be a good time to request
all my notes from the hospital.

A lot of people have said that. Apparently there's an ocular muscle
consultant at the hospital... that's who Im waiting two months to see...
but no one's giving me the information in the meantime.

I'll have a look.

Ahh. Makes supreme sense. Thanks for the simple explanation.

Oh, erm, bad choice of words I think. I mean, when you've had the
cycloplegic drops for the eye exam, forget the end results, but what is
it normal for you to physicall see in terms of vision?

Should the following be normal?

Exophoria means OUTWARD deviation. Phoria means that it displays when
one eye is covered and returns to straight after the two eyes are
unobstructed.

By the way, you do not have decompensating exophoria, you have
convergence insufficiency exotropia, which means that it breaks down at
near. It is quite common and I fix these on a regular basis.

Forget 4dot tests and crap like fixation disparity. What are your
fusional reserves? Have your OD assess you with a prism bar (not rotary
prism on a refractor head) to see at what level of base out prism your
fusion breaks. Also what is your phoria? Is it in the 10-16^ range?

There is a good chance based on this info that you simply need some
vision therapy. You need to find a behavioural optometrist who can
treat this.

Try www.covd.org but unfortunately not too many behavioural optoms in
the UK as they are very classical in their teaching.
