Gary Heiting, an optometrist and associate editor of the site All About Vision, says yes.
“A key factor in something that’s called computer vision syndrome, or just eye strain from computer use, is screen resolution,” Heiting says. “The new iPad, with twice the resolution of the iPad 2, 264 ppi (pixels per inch) instead of 132, people are going to notice less pixelation, especially in a small typeface. It’s not just an enjoyment issue or an aesthetic issue, but it’s definitely a visual comfort issue, over time.”
Trust me, reading text on the new iPad is a pleasure and significantly better than the first two iPads. The new iPad’s Retina Display really is all about text. Even if it doesn’t pop the first time you see the display, reading on the new display is much easier to do for extended periods of time.
You don’t get that feeling of wanting to get away from the display like you do with lower-resolution displays. I often find myself not wanting to read long articles on my desktop monitors, and that’s a major reason I’m always using Instapaper to save those articles and read them later on my iPad. Reading on lower-resolution displays is taxing.
But it’s not just the resolution — it’s the pixel density. That’s what really matters. Apple is rumored to be coming out with laptops with higher pixel density displays. Everything will be the same size, just higher resolution, richer, easier to read.
It was always jarring going from the iPhone 4’s Retina Display back to the iPad 1. The lower-resolution display looked fuzzy and pixelated. This requires your eyes to work harder.
You do not want your eyes to work harder.
