Brief description
In the very beginning of the game, Adam is severely wounded in an attack on the Sarif offices and laboratories. He's augmented (artifical - and more capable - organs) to save his life. When Adam returns from his post-augmentation leave, he has an issue with his retinal prosthesis in that it's slightly glitching and not displaying everything it should. He goes to Francis, head of cyber-security, who says that the "left and right imaging processors weren't completely in sync" and helps Adam fix the display with a reboot: "Your retinal display should be fine now. Its recognition software won't be picking up hostiles yet, but you should be seeing radar and targeting reticules. Biomedical data, too, if you're in pain."
