Recently I had both my eyes operated on for cataract. The surgery itself was a cinch, healing went well.
I now have my new glasses as well, varying in strength from correction for reading and computer, to almost no correction for distance. Because of a special offer, I got a second pair of glasses for reading and computer, and just the other day discovered that they are not colour-less.
I was fixing a photo on the computer, and managed to get a finger-smudge on the lens. Took the glasses off to wipe clean, and that's when I realized that the whites on the computer screen were whiter and blues bluer than with the glasses on.
I believe it is the anti-reflective coating that does this.
Moving the glasses up and down in front of my face and looking through and then over them at the screen, makes the colour quite noticeable.
I haven't checked yet, to see if this actually makes a difference in say, adjusting the white-balance on a photo.
The funny thing is, that the "every distance" glassed with the Transitions coating does not have this colour difference, while the ones for reading/computer do.
Just thought I'd let everyone know, there are a number of us on the Hog that recently had cataract surgery, or will soon have it done. Something to discuss with your ophthalmologist or opticien.

My optician recommended getting drugstore glasses for the computer. They do not have the tint, they are cheap and you can get the lower diopter to compensate for being a little further from the screen.

The opthalmologist concurred. Said that I didn't need the cost of fancy frames and coatings for the computer because the light source is much stronger than the reflect light from a book or other closer item.

I notice that using my "reading" glasses on the computer, the images are not quite focused or sharp. Using the drugstore glasses, the screen is much better.
