I didn't have late afternoon tiredness or headaches, but I noticed that sometimes after staring at a computer screen or TV for a long time my eyes would get entirely bloodshot. It would last about 2 days before it finally cleared. I would also get a pain, but it felt like it was my eyes rather than a headache.

It turns out my one eye has a slight astigmatism (I think that's the term) but it's just enough to need glasses for driving and TV watching. With my computer I've made adjustments so I'm not overly concentrating with my other eye. It had been about 5-7 years between my last eye exam because I thought I had 20/20 vision so sometime in between there I developed problems.

So even if you think you have 20/20 vision you still might want to go get an eye exam periodically.
