[toni-a]

I've been calibrating my screen for years but now... I found that my new glasses aren't perfectly neutral (to be more precise, my everyday glasses cast a slight warm tone, while those for reading a cold tone, but I don't use the latter when I'm at the computer).
How this should be taken into consideration? I mean, the simplest thing would be removing the glasses when doing the white balance, but in this way I can't see the photo sharply — it's annoying not to be able to see the final look of the photo on the whole.

What are you using to calibrate the  screen ? if you are doing it via a hardware device it's not an issue,  even if the glasses have a slight color  cast, the lighting in the room can also change our perception of color, even the wall colors have an effect, to decrease this a screen hood is useful.
If you are not using a hood and you don't have a problem then the glasses color cast  issue should  be totally negligible.
In Lebanon I do my editing in a room with blue walls, the colors on screen are okay but on paper when looking at them they seem totally off... I take the photos  to another room to verify color accuracy.
