In the pantheon of poisons, nothing — not hemlock, not dragon scale — is as dangerous as night shades. Really. Wearing sunglasses after dark will kill your social life on contact.

There is, however, one known antidote: the new collection from Salt Optics.

Classic aviators get an update in gold, silver, walnut, or black titanium frames. Hand-formed acetate in solid colors and tortoise take on retro rocker (the Oslo, the Chuck), modern luxury (the Natali, the Charlotte), and sportos (the Fastback).

The secret ingredient? PFV (Prism Free Vision) Lens Technology, which provides eleven layers of protection for your peepers (including polarizing, antireflective, UV, and hydrophobic).

This potent wisdom can’t help everyone. That guy wearing iridescent wraparounds from the E-Z Mart is too far gone.

But you can save yourself.

Available at Fred Segal Eyes, 500 Broadway, at Fifth Street, Santa Monica (310-394-1875). To see styles, go to saltoptics.com.
