I've been on my iPhone ever since summer started, will this blind me?

Not 24/7 but when I wake up I head for the iPhone, if it needs charging I head for my iPod touch, that needs charging I head for my iPad, If I get bored I watch tv, if I get bored I head for laptop, and the cycle repeats daily. All my friends are on vacation and I won't go to vacation until July -.

No, this will not blind you, but it is still horrible for your health. Go to the beach, the park, or even for a nice bike ride!
Hope I Helped!

Not really but It's not healthy neither to be looking at a screen all day. Pick up a book or learn Japanese… あなたは今日本語を習い始めるべき。

Screens, TV etc, have no effect on eyesight. Worse taht can happen is eyestrain adn that is temporary. Your overall health is another matter. You need to do some exercise in a day to keep your body workign properly.
