eyes get blurry when on the computer

the screen has nothing to do with FPS frames per second, your video card does, my guess is he's on a 15 year old Fred flintstone computer, got to get glasses and a more modern rig.
The screen has everything to do with FPS or refresh rate! in a computer, using a screen only capable of a 60hz refresh rate with a video card capable of 120hz (or vice versa) still only gets you a 60hz rate. refresh rate is how many times the whole screen is redrawn. about 80% of the human population cannot tell the difference between 60 and 120hz systems.

Now, The blurring is nothing but the eye trying to protect itself. Most people may not notice that they will start blinking more the longer they stare at a screen. The one person is correct that the eye is not designed to stare at a constant object for any length of time.

The use of blue light filters help as The blue light produced in a screen creates the highest intensity light in an RGB signal. the filter screens some of that out.
A low power reading glasses do one thing, it will help the eye focus, letting the eye relax better.
Turning the brightness down helps most people but not all.

and the guy was right when trying to say between a scope and a computer. Both can cause eye fatigue if you stare at something too long.

you do know that they no longer advertise a TV with 120 HZ refresh, that's because there is no such thing, please tell me what device doubles the HZ?
 
Maybe try cutting back on the porn, rifle porn that is :cool: or make sure you aren’t becoming diabetic and needing new glasses

TV signals have never been at 120hz and only run at 60hz, monitors still can have a faster refresh rate. It is negotiated between the video card and the monitor during computer initialization.

in fact, my computer is running at 1920x1080p @ 100hz refresh. the monitor being the limiting factor.

Now to add, refresh rate only is how many times the screen is rewritten to.

Drugstore readers aren't always a good solution. Sometimes both eyes are not the same and require different prescriptions.
I needed prescriptions to do my work all day and my eyes are different.
Generic readers that work for my left eye are fuzzy over the right and vice versa.
 
Two pairs of glasses and a free eye exam for $149...you have to stick with their frames and say, "No" a bunch of times. The price goes up every time you forget to say, "No"

 
I have that problem looking through a rifle scope for more than 15 or 20 seconds, particularly on the higher magnifications. I have to look away, and then get back on the scope. It seems to be worse on big objective lens scopes. I think it's eye fatige
Have you noticed that it's just the magnified image that blurs? Reticle stays in focus?

That happens to me (and has happened to buddy of mine as well who is much younger at late-30ish), usually later in the day. I have no solution for the problem (though focusing on a distant object for a few seconds to a minute or two seems to help.)

You can run 60 HZ video signal at 120 Hz; you simply draw each single frame twice. Does nothing for "smoothness" but reduces flicker (which I'm not convinced you can see at 60 Hz anyway - 30 Hz you can though.)

TV signals have never been at 120hz and only run at 60hz, monitors still can have a faster refresh rate. It is negotiated between the video card and the monitor during computer initialization.

I thought the original TV format was 30 Hz interlaced (i.e. odd lines drawn on one pass, then even lines on the next, yielding a complete screen at a rate of 30 fps?) Don't know what the digital TV runs at - never looked into it, as it just works.

you are right but we call it a 60hz interlaced signal meaning it takes 2 passes to get one screen for a refresh rate of 30 fps. Digital TV did not actually change the refresh rate but added the ability to run higher resolution pictures along with adding the ability to run both interlaced (2 pass) and Progressive (1 pass) signals over the air.

Reticle stays in focus. It's the target and surrounding areas that will become, not blurry so much as just kind of indistinct, kind of all melding together if that makes any sense. Maybe that's "blurry."

Yeah; exactly what I'm referring to. Please post if you ever find and explanation and/or cure, because I haven't yet.
