When I look at the center of a wide screen, the edges are out of focus. Bringing them into focus requires moving my head to the side, making the other side even worse. The result: my head is popping back and forth like I am controlled by a drugged puppeteer, I get headaches, and generally grouchy.
I can't even use a 4/3 monitor bigger than 19", and a 19" one must be at least 2.5 feet from my eyes.
I am certain that I am not the only one in this situation, as it comes with age.  |
Welcome to my world! I do wear trifocals. I tried the progressives when I "outgrew" (?) bifocals about ten or so years ago and hated the stupid things. I didn't mind the head bobbing bit so much but the way straight lines suddenly looked curved drove me nutz and almost caused me to have accidents when driving forklifts at work. I switched to trifocals and love them but they aren't perfect. At the movies, I have to hold my head rigid to keep the correct lens in place and it looks like I'm watching through a window so I just don't wear them then. My distance vision is fairly good so I can get away with it.
At home, I have a pair of glasses just for watching TV when laying in bed since I would be looking through the wrong lens if I wore my trifocals. I don't have enough astigmatism to be noticeable (I'm lucky, my Daddy had it bad) so I can get away with inexpensive drug store readers.
When I worked at my computer, I found I was killing my neck to look through the correct lens and having to move in close or back off, depending on the lens I used. I got some drugstore readers that allow me to sit 15-20" from the screen and still be able to read copy on the desk (I can't move it too close without going blurry). They have worked out great. My neck is much happier.
