I'm 16 and my vision is horrible, will it keep getting worse as i age?

A little bit: You are probably myopic and most who have this condition think their eyes are "horrible". Few are however since most are correctible to normal. Myopia progresses at a steadily slower rate through the mid 20s and then stops. But the changes are less each time. As your ophthalmologist next time you get examined to put your power in perspective.
