Binoculars

If the distance were cut in half

And you could do simpler math

If the angle were cut, I'd still appear obscureThe closer you get to me

The further away you'll be

Better to secure a set of binocularsIf the ocean were not so deep

Then onward to me you'd creep

Only to find, I'm even more a blurI don't mean to be so cruel

Hold you to all these rules

But I would prefer, you use your binoculars
