Well, mostly people don't ride in the drops when not going downhill, plus often the gradient changes around corners - steep in/shallow out, which means looking ahead is looking up - on the descents I do, anyhow.
Bars with shallower drops might help, as might larger cycling-specific sunglasses as suggested above. But also, the flatter your back is, the less your neck has to bend up. Rotate your hips forward to straighten your back. Also reduces wind resistance.
