(I did read your OP, but given some suggestions above, I'll post this anyway.)
If you are a Sorcerer, Battle Sorcerer or Stalwart Sorcerer, you can take Sorcerous Heritage Feats (CompArcane, PHB2, Dragon Magic). In particular, the feat Infernal Sorcerer Heritage opens up that particular line, and Infernal Sorcerer Eyes would be available as soon as 1st level for a Human:
Follow that up with Infernal Sorcerer Howl and you'll have a Sonic attack in a 30' cone that does 2d6 damage per spell level used.
If you go for the Draconic Heritage (CompArc) instead, you can qualify for Draconic Senses (Dragon Magic):
Again, a human sorcerer could get this particular feat by 1st level, but until he got to third level, he would not qualify for the first boost in the feat. Still, there are a lot o nifty Draconic feats- one gets you a breath weapon (similar to the Infernal one above), another gets you additional spells, and so forth.

As a swift action, you can expend a spell slot to cause your eyes to emit a spectral red glow. You gain the ability to see perfectly in darkness of any kind, out to the limit of your line of sight. You ignore the concealment provided by darkness spells and effects. This benefit lasts for 10 minutes per level of the spell slot used to activate it.

If you go for the Draconic Heritage (CompArc) instead, you can qualify for Draconic Senses (Dragon Magic):
Your draconic blood grants you great sensory power.
Prerequisite: Cha 11, dragonblood subtype.
Benefit: You gain low-light vision and a bonus on Listen, Search, and Spot checks equal to the number of draconic feats you have.
Special: If you have three or more draconic feats, you also gain darkvision out to 60 feet.
Normal: If you have four or more draconic feats, you also gain blindsense out to 20 feet.
