In case you are interested in "eye realism" take a look at this paper. They try to model what is actually going on in biological eyes.
That's actually pretty old. I read into it a few years ago. I'm still just concerned with how specular highlights can be affected by material in a way that causes a blooming effect. My house has a lot of big windows, but today the cloud cover makes it shady. When I can I'll try to capture this effect.
Back on topic:
Here's a screenshot of BF4. I've manipulated it to look how I think is more physically accurate.
Look for differences on:
> The Tires
> The Sun Flare
> The Explosions
I recommend you open the two full size images and swap between the tabs to see the differences better.
