Hi,
Relax! It is incredibly unlikely to be connected to him going outside in your garden! If there is anything wrong, he had it before you brought him home. Keep taking him outside every hour or so during the day just as you are doing - treat him in the same way as you would if there wasn't a discharge from his eyes, until the vet tells you different. How is he in himself? Is he active, eating, playing? Are his poos normal? Or is he sleepy, lethargic, tetchy? Does he have the runs?
