I have enough of astigmatism to have it corrected in my glasses and yet the colour scheme I found the most comfortable over the years is Zenburn. Though I do prefer the high contrast version with darker background.

The only time I managed to use a light theme for an extended period of time was a couple of years in a room with weird lighting and reflective screen of an imac. That's when I was using Solarised Light, because my Zenburn just couldn't provide enough contrast.

Then I moved to a different room and it was back to Zenburn.
