Eyes! I love my eyes and I afraid of having glasses on my face?

Actually. I love my eyes, because they look so amazing!
So the question is. I'm joining in merchant navy this year and I want to have 6/6 eye sight. I could appreciate do and do nots to keep my eyes bright and shinny!
I usually use my iphone 4 under my blanket whenever I'm about to sleep! I just love surfing and it became a bad habit. I want to get rid of it. Will this really effect on my eyes? And when I wake up. I just check out my phone first and just check out mails!

So will all these effects my eyes? If yes. Then suggest me to how should I have to be?

Probably not, just take care of your diet.eat egg
