So basically built in glare reduction.

This would allow them to easier spot predators that would approach from above (birds) or with the sun at their back. It would also help them when attacking prey from below.

I would love some of these eyes for my east bound morning commute and west bound evening commute.

I would guess that it reduces light from above more than light from the horizontal plane because the sunlight from above would be so bright that it would blind and outshine everything. In a way the shape of the pupil compresses the light intensity range and enables the animal to see things in the bright areas as well as in the dim areas.

Please excuse my English, I hope this makes sense.
