If you've looked at a computer-screen, you've probably sometimes seen a line cut across the screen from top to bottom.

Now, I just saw a line in front of my field of view when I was reading a book!

What caused that?

What are your eyes running on - VGA or SVGA?

Also, try adjusting your vertical hold. There should be a switch behind your left ear - twist it until your vision rights itself.

Can't say I ever noticed such a line, but you know when you been playing games too much, and you see the sun momentarily glinting off a window and you think 'Wow, realistic graphics'
 
:roll:

I see points of light in my vision and sometimes streaks. Almost like a meteor falling through the sky. It doesn't happen often, but I think it's a natural thing. Or I think so because I've been seeing them since I was a kid and still have perfect vision. Maybe you just had a streak like this that went vertically so it appeared like a line from top to bottom.
 
Sometimes when I'm reading I see lines and streaks and it reminds of me of this optical illusion...

Try wearing a cap to keep your hair out of your field of vision. Let us know if the problem recurs.

II can't see it or doesn't believe it exists.
 
Could it have been the line between the left and right pages of the book?
perhaps you could provide more details.

Could be Vitreous Detachment .
Alternatively Retinal Detachment but this would probably have turned you blind by now seeing ( :cool: ) that you haven't had this diagnosed and treated

It was not a vertical or glowing streak.

If you've ever looked at a screen for along period of time you'ld probably notice a line moving across the screen.

The line is horizontal (from left to right or vice versa) and moves vertically (the horizontal-line moves up the screen from bottom to top).

The thing was that I was not looking at the screen, and I was reading a book called B-58 Hustler (It's a high-speed supersonic bomber developed in the mid-1950's).

I've seen this line before on screens, but not without the screen present.

I've been looking at screens very closely for years, but I don't know exactly what you mean.

There can be 60Hz (or 50Hz) interference, causing banding or edge distortion to move slowly up the screen.


When reading a book, I think fluorescent lights (low-frequency ballast) can cause some effects if you move the book rapidly.

Trinitron screens have *horizontal* lines at about one third and two thirds of the screen height. I understand that these are damper wires that steady the main pixel grid wires, which run vertically. The horizontal wires are best seen when the screen is displaying a plain medium-gray background. Maybe on those screens that rotate to display a 'portrait' layout this would explain vertical lines?
