視力の変化と医師との対話
Welcome to Kevin's English Room Podcast.
Hello.
Hello.
How's your arm, by the way?
Is everything...
My arm?
Your eye.
Oh, my eye, yeah.
Is everything...
Yeah, everything's good. Everything is...
I still have to do the eye drops.
Yeah.
Which I have to do right now.
Go ahead, go ahead.
But like nothing strange or like...
I mean, so...
ハローグレア is one of the...
You know what it is?
It's like a ring.
Last week, yeah.
That's been going on.
But it's a common thing, right?
It is a common thing they said.
After surgery.
Yeah.
But like one big, like one new info that they somehow managed to not explain to me.
Was that they told me it could go on forever.
What?
They were like...
The glare thing?
Yeah, the glare thing.
It was like, you know, doctor, I've been getting...
I'm still getting a lot of glares after a week.
It's like, oh, yeah, about a week.
That's like...
It's like the most glaring days right now.
So you'll be fine.
And most people will be gone in about a month.
Okay.
So just bear with me here.
Okay.
Well, you know, like several people don't get it forever.
So...
What?
I mean, if you don't like it, you can take it out.
But some people get it forever.
I was like, doctor.
What?
Really, doctor?
Yeah, yeah, yeah.
Is it like...
Okay, okay, okay.
Wow.
So I'm sure it's like really, really rare.
I don't know how much...
I don't know the percentage of the people that has the glare forever.
Otherwise, doctor, there's no...
They have to explain it to you.
If it's like...
They did explain to me that there's the halo glare happening.
But said that most will go away.
They did explain it to me, to be fair.
They did explain that...
They didn't lie at all.
People will have the halo glare.
And then most people, that will go away.
Most people.
Okay.
Yeah.
So they didn't lie.
They didn't lie.
They didn't lie.
Okay.
To be fair, I guess they were just a little bit under explanatory.
Okay.
I guess.
Okay.
Yeah.
But the thing is, it really doesn't bother me that much.
Yeah, that's good.
The glare isn't really bothersome at all.
Okay, good, good, good.
If I am that few percentage where I have to live with this forever, I really don't have...
That's good.
I really wouldn't mind.
Great, great, great.
Yeah.
Good, good, good.
Good to hear that.
Yeah, right.
It's not devastating.
It wasn't daunting.
Yeah, yeah, yeah, yeah.
So it's not like nothing hurts.
It doesn't hurt.
Nothing, you know.
I get dry eyes at like when it's later on the day, like at night.
But that too is set to be gone in about a week or so, a month or so.
So hopefully that will be gone by then.
視力の関係
But nothing else.
My eyesight is great.
That's great.
Last time I said it was a 2.0 and 1.5, right?
But my recent eyesight test was 2.0 and a 2.0.
I got a double 2.0.
That's like the...
That's great.
The highest score.
That's right.
That's the highest.
Right.
Oh, great.
So, yeah.
So you see everything very well.
I can see everything very well.
Without glasses, without any lens, contact lens?
Yes, yes, yes.
The moment I wake up, perfect.
That's nice.
Perfect.
That's nice.
Right.
So you throw all the contact lens away?
Not yet.
Not yet?
I don't know what's going to happen, right?
Okay.
Like I still have to make sure that my gaz doesn't pop yet.
So that takes...
I have to scale them after about a month or so.
Okay.
So, yeah.
So until then, you keep it.
Until then, I'm going to keep it, just in case.
Yeah, just to make sure.
Yeah.
Yeah.
Right.
Right.
Did you know that the vision in America is scaled not by 1.5 or 2.0?
It's 2020, 2040, 2080.
That's how America scales the vision.
I've never heard of it.
So 2020 is the same as 1.0.
Okay.
I think Japan just divided it.
Oh.
Oh, is that how you say it?
Yeah, 20 slash 20.
Okay, okay.
If it's 20 slash 40, that's 0.5 in Japan.
Oh, I see, I see.
Equivalent to it.
Oh, so I guess that's the same.
It's the same.
Right.
If you like calculate it, it's like the same.
Right.
And how that 2040, what that means is it's feet, 20 feet by 40 feet.
Okay.
An average eyesight, that's, first of all, in standard, average eyesight is 2020.
That's 2020.
Oh, okay.
So if you're 2040, an average 2020 person can see 40 feet away.
This letter right here, 9mm letter.
A normal person can go further, far up to 40 feet, and they can still see it.
But if you're 2040, you will have to go close as 20 feet in order for you to see that 9mm alphabet or the letter C.
Okay.
So you get what I'm saying?
Yeah.
You have to go closer, double the average.
Okay.
The average is 40, but you have to go to 20.
So if it's like 2080, average person can see 80 feet away, but you have to go close as 20 feet.
That's how bad your eyesight is.
That's how they measure it.
I see.
So I'm 2.0, so that's 2010.
You're 2010.
So you're always going to be 20.
The first letter is always going to be 20.
Okay.
You, you're always going to be 20.
Okay.
Yeah, the average is going to be always the second letter.
I see.
Second number.
So the average person will have to go close as 10 feet, but I can see it from 20 feet far.
So that's how it's interesting, right?
It's how it's measured.
視力の計測方法の違い
So what if like, there are like people who has like zero point.
Right.
For example.
That's right.
So that's 21,000 or something.
Yeah, yeah, yeah.
Right.
So an average person can go as far as 1,000 feet and can still see that letter.
But that fucker who's 21,000 has to go close as 20 feet in order for that, for them to
see that.
Is that like, is that how, is that same as like 0.01 in Japan?
That's right.
That's the same.
Same thing?
It's the same thing.
That's how they measure it?
Well, Japan is a little bit different.
They don't use 20 feet.
And that's different from 20 feet.
So, but the ratios.
Yeah.
Yeah.
It is not exactly, exactly the same, but it's thought about the same thing.
I see.
Because I've been always wondering, like, what is those numbers?
Like, if you have 2.0, does that mean like you're 10 times better than 0.2?
Is that like, how, what's the numbers?
Like, how?
Right.
Yeah, but.
Right.
Okay, that's how it works.
Right.
I see.
So 0.01, you have to go like 2,000.
2,000 feet.
2,000 feet.
Where, for example, like if I have 1.0, then I can stand 20.
20, 20 feet.
I think that's difficult.
Feet.
I can't, I can't, I can't imagine like which, how long is the 20 feet, but.
Yeah, 20 feet is 6 meters.
6 meters.
Yeah.
Yeah.
Okay.
So if you're 0.01, I guess Kakeshin is somewhere around there?
Yeah.
Around there.
So, 2,000 feet.
Okay.
That is, that's about 600 meters.
Okay.
So if I have 1.0 eyesight.
Yeah.
I go 600 meters away, and still I can see the world?
Yeah, that's how big the, so if you, if something is 600 meters away.
Yeah.
And you can still see it.
That size has to be really big.
Oh, I see.
That C has to be really big for you to see it, right?
Yeah, if I have 1.0, yeah.
Yeah.
But for Kakeshin, he has to go up to 20 feet.
For the same size?
For the same size.
Whereas I'm 60, wait, wait, 600 meters away from the board.
Yeah.
And still can see it.
Yeah.
He has to go like.
0.6 kilometers is 600 meters, right?
Yeah.
Yeah, yeah, yeah.
10 feet, that's like, 10 feet then.
10 feet?
Yeah.
10 feet is.
About 30 meters?
3 meters.
3 meters?
10 feet is 3 meters.
It's devastating.
It's.
It's devastating.
It's really, okay.
Yeah.
I've been always wondering, like for those like 0.6, 0.2, or like 0.01, it's like how.
How.
Different, is it?
Yeah, yeah, yeah, yeah.
But that makes it more easy, easier to like visualize.
Yeah.
Yeah.
Right, right, right.
I didn't know that.
Oh, it's really different.
600 meters?
And then, okay.
視力測定の基準
That's pretty far.
It's pretty far.
Yeah.
And he, 0.01, has to go.
20 feet.
20 feet?
Wow.
Yeah.
I thought, so I was, you know, for TikTok, I was researching why the hell it's like
1.5 or.
Yeah, yeah, yeah.
Why it's just 20, 20, and that's how we discovered that, and it was interesting, so.
That's.
Right.
Wow.
Yeah, so.
There you go.
All right.
Thanks for listening, guys.
Thank you.
Bye-bye.
Bye-bye.
Bye-bye.
Bye-bye.
