Ask HN: Do your eyes bug you even though your prescription is
"correct"?
I'm digging into an idea around eyeglasses, screen-time, and vision
discomfort. If you wear prescription glasses but still get
headaches, eye strain, or blurry vision after long screen days, I'd
love to chat briefly (20-30 min). Pure research, zero selling.
Interested? Drop a comment below or email me directly at jbornhorst
[at] gmail.com. I'll coordinate a convenient time to talk.

| For example, at age 50:

| an issue with my 600 yard shots clustering in three places -
| one cluster right in the middle, another cluster directly left,
| and a third cluster somewhere else
|
| You set up these camera thingies (https://scattusa.com/) and it
| shows you an exact trace of what's going on with your aiming,
| while not using any ammo (recoil hides a lot so you do most
| practice without ammo).
|
| The left cluster ended up being super obvious: trigger control
| and problems relaxing, making me physically jump shots over
| there - you could see lines from the Scatt go right after shot
| breaks.
|
| The _other_ cluster though was strange as hell. It was just not
| in the right spot. But it was a singular spot, I had two
| remaining clusters. There was no movement between middle and
| other cluster like there was with the left. It just looked like
| some percentage of the time I aimed at the wrong spot (not
| _that_ far off, but enough to drop points).
|
| Then one day when lying on the ground for an hour with the
| Scatt, I started seeing double. I'd blink and it would go away,
| but by relaxing a lot I could make it go back. The double
| vision was right where the cluster was.
|
| Then I looked up more info on astigmatism (had >2 diopter
| astigmatism?), and it turns out it's literally just light
| refracting into 2+ places instead of 1. And of course the real
| bullseye people know about this (since in high power honestly
| we're kinda pretending at it), and they have specialized sights
| for correcting the axis and magnitude of astigmatism:
|
| https://gehmann.com/en/579-Cylindrical-lens-system-0-2-Spher...
|
| And sure enough, that's like the same thing the optometrist is
| doing. Except in the context of bullseye you can _physically
| see the 2 bullseyes floating around an axis and then coming
| together_.
|
| I get why they do it the way they do it, because your brain
| corrects the astigmatism and doesn't let you see double
| normally, but if you can train your eye/brain to kinda
| dissociate and see double, you can get a pretty exact
| correction for astigmatism.
|

| _Post-concussion syndrome (and screens)_
|
| After getting a concussion, I had to change my screens in a big
| way. Many people have heard of sensitivity to PWM and low
| frequency PWM in particular. The alternative is DC dimming, and
| it helps tremendously. Additionally, higher refresh rates seem to
| help. At least 120 Hz but preferably 144, 165 or higher. My phone
| has some complicated PWM / DC dimming settings[0] - possibly 120
| / 360 Hz[1]. My laptop is 165 Hz and does not appear to use
| PWM[2]. My desktop screens are 144 Hz and have DC dimming.
|
| I'm going through the hassle of getting a physician to sign off

| better screens at work, as they provided a laptop with a horrible
| 60 Hz screen, and two crappy 60 Hz monitors. Fortunately I'm only
| in the office twice a week.
|
| _Glasses_
|
| Last year, I got brand new glasses with the prescription
| determined by the optometrist. However, it took _three tries_ of
| adjusting things like pupil measurements and the "base curve" or
| index of the glasses before I started to get used to them. Up
| until then, I felt very _tired_ and brain foggy while wearing
| them. With the third revision and a week of adjustment, I finally
| started to settle in. It takes a really good eye doctor to figure
| out these kinds of issues, and be willing to swap out lenses for
| you.

| Anecdotes
|
| (1) A doctor in SF put me in the machines, measured my eyes, made
| me some glasses. I come back a week later and using them is worse
| than not using them. I tell them they don't work. They get upset
| and reprimand me. Finally they give in. Make a new appointment. A
| week later doctor sees me, makes a new prescription, orders
| glasses, a week later the same, using them is worse then not.
|
| Again they get angry an berate me. They give my some BS about I
| should take them home and let your eyes get used to them. I
| respond, if that's the case then the doctor could not make a
| prescription with his machine because I'd need to take the
| machine home to "let my eyes get used them" before he'd know if
| it was working.
|
| Anyway, they finally let me make another appointment. the doctor
| measures and claims he knows what must have happened (didn't tell
| me) and orders another pair. A week later I check. These ones are
| marginally better than than not wearing anything AT THAT MOMENT.
| It take them home, every time I try to use them they're worse
| than not using them. (oh, and they apparently charged the eye
| insurance $999)
|
| (2) My previous SF doctor I had a similar experience in that
| their glasses didn't work. They didn't berate me. They re-ordered
| once. I was shy and didn't complain the second time even though
| they were no good and I never used them.
|
| (3) I've bought lots of glasses at Jins (Japan) - They have fully
| automated machines for measurement. I've got 2 pairs from them
| that help the most often, though not always.
|
| (4) Last time I bought glasses I was at ZOff in Japan (because
| the wait for Jins was too long). The "doctor" their claimed my
| eyes were fairly good - meaning the images are clear, it's only
| the double vision that's the issue (letters look like there's a
