Can being near-sighted come from genetics?!

Can being near-sighted come from genetics?

I know it isnt the computer messing up my sight because my screen is on LOW. But, at my school, there was an eye exam thing and i failed....so i'm wondering if being near sighted can come from genetics. Both of my parents are are near sighted (well my mom had laser eye surgery) and most of my cousins wear glasses. But i really dont want glasses because i already have braces which are good enough for me! And i was depressed before about because i thought it was because i wasnt taking care of how i treat my eyes. Should i blame myself or genetics?

I know when the school sends my reccomendation to see an eye doctor she will blame me! so thats why im sooo beat up about it. Even if it is genetics, i cant absolutely prove it to her.

genetics play a part in myopia
