Having trouble with my eyes focusing on a Retina display. Am I alone?

I picked up the 13" MacBook Pro Retina yesterday, but I think it's going back today.

For starters the onboard video card means that almost 1.5GB of system memory is being used on the kernel alone. Doing some research I found out that that was because of the needs of the Retina display and the onboard video card. In other words it could be solved with a discrete video card and maybe more ram, but you're deep into the $2000+ range when you look at that since the 13" models don't have discrete video cards.

The worst problem, though, is eyestrain and a weird sort too. I remember feeling something similar the first time I saw a Retina iPad (I've only ever used standard iPads, first the iPad 1, iPad 2 and now the Mini). It was like my eyes struggled to maintain focus on anything because it was so bright. But then if I turn the actual brightness down it's hard for me to make out text. I've read about other people voicing trouble with the Retina displays on other forums. But I would be curious specifically about having trouble keeping your eyes focused. It's really distracting. It's not at all like reading "paper". It's not even like reading my Kindle or other devices intended to resemble that level of clarity.
