Can having bangs that fall in front of your eyes can give you a lazy eye? This fear was sparked by a "leading Tasmanian optometrist" named Andrew Hogan, who told Australian tabloid the Daily Telegraph that trendy haircuts covering one eye might result in lazy eye (amblyopia) among youths:
Turns out all that warning was for nothing. As MSNBC puts it, one amblyopia specialist named Dr. Leonard Press could barely "suppress a chuckle" after hearing about the rumor.

The thing is while amblyopia is a serious eye problem, it's mostly young children who are at risk. The problem needs to be corrected before they're about seven, or it becomes very difficult to change.

Once we're past that age, our brains and eyes are pretty much trained to see the way they see. So if you made it this far being able to see out of both eyes, blocking one partially with your bangs is not going to make your vision disappear.
