I should probably have posted this on an opticians' website but, since color vision is so important to me as a photographer I am asking this here, hoping that somebody has an answer.
I just got new glasses, with high-index lenses, and for the first time in my long life, progressive lenses rather than bifocals. I do lots of photography and post work on the computer, and I seem to have adjusted quickly to the progressives. Now, I can actually *read* the text on my NEC 3090, which is more than 2 feet across my desk.
The problem comes when I look at images projected on a screen, and also when I drive. There seems to be a color fringing effect. For example, when I look straight ahead but shift my eyes up toward the top of the lenses, the tops of trees far down the road seem to have a red/yellow fringe on the tops. Looking at the screen with projected images, I also notice some color fringing that goes away if I move my head up or down a bit. All of this stinks, because I have to see accurate colors.
Are these problems because of the progressive aspect of the lenses, or of the nature of the high index glass (plastic, I guess)? Or did I just end up with some poorly designed/ground lenses?
