Is this a good technique to defend myself from a fist fight?

I am 14 and i had a fight earlier and when he fought against me i didn't fight back i dodged him so this is what i did im blind in my right eye and i covered it up when i do that my senses on my right side sharpen and i kept it covered he charged at me and i kept flipping and rolling out his way his friends tried holding me still he picked a fight with me because i never retaliate to his threats his friends say im no good but i never really talked to him before did i do the right thing ???
