@l'électeur Ah no no, I'm talking about the "teen slang" tag that the author of the question added. I think it's not completely correct, and we probably don't need a new tag for this. Your comment was very helpful.
I would edit it but I don't feel comfortable reverting back what was just added... Like you know on Wikipedia they have edit wars... I'm not sure how to handle this.
I think it's great that we have knowledgeable people like you here, and it's always very interesting to hear what people actually living in Japan have to say. :)
I am having trouble translating this sentence because of ても.
そんなにゲームばかりして、目が悪くなっても知らないわよ。
Does it mean:
If you only play the game so much, your eyes will get bad even if you don't know.
I am not sure if that translation makes sense or is correct.
