|Tuna as a treat is just fine.
Tuna may cause kitty to go blind if that's all you feed them--it's because tuna lacks taurine, a fatty acid necessary for eye health. A cat will not go blind from tuna as a treat.
Tuna also contains mercury, and should be eaten in moderation because of it, but other fish contain mercury too. Kitties, and humans, should only eat oily fish (tuna, mackerel, swordfish, shark) a maximum of two servings a week (a serving for human being a can of tuna or equivalent, less for kitties). Once a week is better if you're worried.
Everything in moderation and you'll be just fine. Have you tried drying your own meats? There are instructions on the internet for making chicken, beef, etc jerky.
