Egg Goggles

The Egg Goggles are recurring objects that appear in the Sonic the Hedgehog series. They are a pair of goggles that are often worn by Doctor Eggman.

Appearance
The Egg Goggles are black, metal goggles with green lens. The eye pieces are octagonal in shape, and are held together by a metal strap.

Features and traits
Though not often used by Doctor Eggman, he has shown to wear these goggles over his normal glasses when engaging in combat in the Egg Walker, which may hint at them functioning as some sort of aiming peripheral akin to the lock-on device on E-102 Gamma's head.
