Optic weaponry
Optics comprise a mechanoid's sense of sight, feeding video data to their other systems. However, many mechanoids enhance these structures by installing optional weapons systems. Common examples include beam or partical weaponry, especially lasers. In these cases a robot can quite literally shoot what it sees.

Laserbeak contained optic lasers in his eyes, using them to both spy on the Autobots and rain death upon them. He used them to blast a window of Shawn Berger's office, allowing him to take the corpulent businessman to the Decepticons. Megatron's Master Plan, Part 1 Laserbeak also used them to open doors and potholes while in New York. City of Steel
Beast Wars
It seems that almost all Predacons have optic lasers which they used at least once during the duration of the show. Waspinator, Terrorsaur, and Scorponok are all good examples.
Dinobot's optic lasers appeared to be tied to his own Energon supply, making them potentially risky to use for too long. Indeed, Dinobot exhausted the last of his energy to destroy the Golden Disk with his optic lasers, sacrificing his life. Code of Hero
