Hearing Better

In this OP you are going to see much hypothesization, don't read it if you don't want to.

A year ago give or take my hearing was so bad you might as well email me, I mean from two rooms away. When I listened to my stereo when the rest of them left at a certain dB the sound came clear. It was as if my ears opened up.

Well now tonight at 4:00 AM it was very low. I could understand the words and hear the timbre, like the cymbals n shit.

And eyesight. Still some days are better than others. I have had both done for cataracts ans they were corrected well. I was nearsighted all my life but now I have 20/20 at distance. I need readers, who around is 59 and doesn't ?

Still though, there are days I can't hear so good and others I can. There are also days when I don't see so good and others I can.

I got some weak readers, 1.00s and wear them out and about. Going out walking I can see a quarter mile with them on, and other times, more in the past it was blurry past like 15 feet. I got 3.00s for working on stuff close up.

Now it gets thick. Remember most is supposition or hypotheses.

Hearing and seeing are instrumental to our survival.

Now quick at eyesight, they can do wonders with the mechanics of the eye, but they cannot make you a new retina. I really would like to know which minerals feed them.

Now hearing, they can do wonders with the little bones in there. This quite renowned Dr. Stoller built my friend's ear out of stuff he cut out of his leg. But back then there were no cochlear implants.

Anyway, there is not so much easy problems with the bones and eardrum, and if so you know it. Back then your natural cochlea was the only option.

I say that the cochlea being the crux of the matter it what needs to be addressed. First of all I believe that as we age those hairs break off. I believe that if we have a god diet and are well nourished we will grow new hairs in there.

HOWEVER, the old dead hairs are floating around in there. That has to impair hearing. And I am fairly sure there is no practical way to remove that.

So I can see and hear well one day and not the next.

Hmmm, I never thought about if they correlated...

Tear it up.

Not me. I had the cataract fix and elected to have one eye focus at
10" and the other about 24". So I can read and compute and solder
without glasses. I use glasses when I drive.

Yep! It's a miracle. They removed floaters in one of my eyes when they
did the cataract surgery. That eye was always worse, but now it's better
than the other. The other one they made nearsighted like yours, but I
wish the focal point were a little farther away.

Can anybody else control which eye you see out of? Not that anybody else
tries. I might have picked up that ability eons ago when a teacher
explained how to tell which eye is dominant.

Brains are pretty good at making a clear image from whatever comes in
from both eyes. Things look sharp to me if only one eye is in focus.

You can always get reading or computing or driving glasses, so having
two eyes at different fixed-focus points does no harm.

Don't you get a headache with eyes set at different focal lengths?

I never get headaches but one afternoon working at my PC felt different.
When I reached up to take my glasses off I discovered that the lens had
fallen out on the right side. I am left eye dominant so didn't notice at
all except for the slowly developing headache. Careful searching on the
floor found the missing lens unharmed and I refitted it into the frame.

You can live fine with one good eye and one badly blurred one but you
lose any sense of depth and 3D movies are a complete waste of time.

You can always get reading or computing or driving glasses, so having

I found it most unpleasant after just a couple of hours working. I
prefer to have glasses for close working, TV distances and driving.
My corrected vision is something like 40/20 so I am very sensitive to
anything that isn't tack sharp. Left eye is noticeably better.

As a youngster I could on a good night split epsilon Lyra naked eye
which is a 3' arc equal double star. Easy with any optical aid.

Floaters are inhomogenities in the vitreous body, and large floaters
(as in my case) are often the result of posterior vitreous detachment.
Did they remove the vitreous body?

My eyes are quite different (L -4, R -7.5) and I probably got glasses
way too late, so the brain was trained early on to look at near things
with the right eye, and to use the left for things farther away.

With 45 or so I tried glasses with progressive lenses for two months
and hated them, then I got glasses that had the focal point at infinity
for the left and to about 60 cm for the right eye. This works very well
for me, except that now, with 62, the ability to accomodation got worse
and I have reading glasses, too.

This is called "monovision" in the trade, and it works well for
some, and not at all for others -- they get a headache. For people of
the first type, it works with glasses, contact lenses, and intraocular
lenses. A 40-year-old coworker with slight presbyopia has his eyes
lasered like this.

Does anyone have multifocal intraocular lenses ?

I had a vitrectomy in one eye, surgery for a serious retinal detatch.
They slurped out the vitreus humor and pumped my eyeball full of
pressurized Freon, and my body gradually refilled it with, basically,
saline; different refractive index. Some laser spot welding keeps the
retina attached now. It was really strange for about a month. The old
big floaters disappeared, except for a few really tiny dots.

It's amazing that they can fix stuff like this.

I considered that but decided to just let them correct it to 20/20. It is nice like when outside, you can see way down the street with depth perception and no glasses. I can't wait to go to the shooting range, there just isn't one around here.

But then I do have to use at least two different strengths of readers, one for working and one for like the computer, the grocery. The ones for like when I solder are 3.00 and my regular ones I got some 1.00s and 2.00s and am not sure which. In fact sometimes I forget if I am wearing glasses.

Brains are good at that. Humans have very poor eyes but our brains have more processing power. Aware of it or not your brain is building an image of your surroundings piece by piece as the eye pans around. Even if you were to be fixated on the TV, when someone walks in the room you shift your gaze and the brain has a little bit more information.

I don't know if I can find the article again and I don't feel like tying right now. You can think up a search string.

That's optimizing resolution for each eye while staring straight
ahead. That's what they like to do.

Mine don't understand that I use both eyes simultaneously, and move
around now and then. They make exquisitely precise corrections for my
focal length and astigmatism, and create glasses that twist the world
around if I dare move my head. I do spherical-only lenses, no cylinder
component, and they work fine. Most of the time, I don't wear glasses,
so I'm adapted to my astigmatism; leave it alone.

I've found glasses-fitting advice online, from the 1880's, that say to
go easy with the astigmatism correction.

That is pretty much what I want though. I do use peripheral vision a lot
and deliberately but my glasses are not used with a telescope.
Interestingly as my eyes fully dark adapt they become closer to a
neutral prescription and I can see more stars without my glasses.

I only have a tiny amount of astigmatism so my glasses are essentially
pure spherical lenses. I think the worst is 0.25 diopter cyl.

go easy with the astigmatism correction.

That was probably more to do with cost benefit when lenses were so much
harder to figure and polish. These days machine made spectacle lenses to
any formulation are mass produced by CNC type machines.

Not really true. If you are blind in one eye, your depth perception goes away, but even a small amount of sight in one eye still enables 3D vision. The eyes only need to see enough for them to track the objects in view to generate 3D vision.

I know, one eye is not even 20/100. The other eye is/was pretty much 20/20 all my life so I never needed to wear glasses to see while they were required to drive. Once a cop stopped me and didn't believe I was wearing contacts (I wasn't). He told me to look to the side so he could see them. I did and he couldn't tell. Maybe he wasn't wearing his contacts!

lol

I still enjoy 3D movies with or without glasses.

I tried them once. They were the worst glasses ever. There was a spot on the lens about the size of a pencil eraser where things were in focus, the position of which depended on the distance to what you were looking at. I would have to move my head around to find the right spot roaming up and down, side to side. I guess my strong astigmatism (4.5 diopters) might explain why they work poorly for me and well for others. The glasses I had as a kid if held at arms length would rotate an object twice as fast as the glasses were rotated. I never figured out why that was.

My optician would prefer me to have varifocals.

I tried them once. They were the worst glasses ever. There was a spot on the lens about the size of a pencil eraser where things were in focus, the position of which depended on the distance to what you were looking at. I would have to move my head around to find the right spot roaming up and down, side to side. I guess my strong astigmatism (4.5 diopters) might explain why they work poorly for me and well for others. The glasses I had as a kid if held at arms length would rotate an object twice as fast as the glasses were rotated. I never figured out why that was.

I've told this before, I have Amblyopia, wore glasses from 5 to 10
years old to correct*.
Several years ago I went in for a drivers test, during the vision test
I read the right eye, then when I wen to the left eye, I said nothing
there, she said oh, there's something there! I closed my right I end saw
and read off the letters. Not sure quite what happened, I'll know what
to do next time.
I wonder If my vision would be better if they had got me glasses much
earlier, because as I see it, it's not so much my eye as a brain/eye
connection. The vision is just different, when I close my bad eye,
everything is fine, when I close my good eye, I can see that I'm missing
something.
Something new, at night I sit in a darkened room and read my computer,
when I get up and go to a darkened area (like the moonlight bathroom) I
can't see anything with my good eye, but my bad eye has dark adapted
vision. After a while my good eye will adjust and I can see in the dim
light.

Yep! It's a miracle. They removed floaters in one of my eyes when they
did the cataract surgery. That eye was always worse, but now it's better
than the other. The other one they made nearsighted like yours, but I
wish the focal point were a little farther away.

Can anybody else control which eye you see out of? Not that anybody else
tries. I might have picked up that ability eons ago when a teacher
explained how to tell which eye is dominant.

I was born crosseyed and never learned to see 3D. I can select which eye but prefer the left as it's slightly far sighted. It is handy when when getting a bright flash as I can switch to the other eye.

What do you mean by "a bright flash"? That describes a symptom of
retinal detachment.

 

Or a neurological disorder.
