見ろ means "you must look"

見てろ means "you must be looking"

見てろよ is omitted word. If saying without omitting, it is 見ていろよ。So ろ is part of いろ。いろ is order form of いる。

Thank you so much sir, I really appreciate your help :) It's such a great privilege to be able to learn more about the beautiful and mystical Japanese language from natives like yourself :)

本当にありがとうございました匠さん :)

Could you please tell me what the difference between 見ろ and 見てろ is? Are they both used for giving orders, for example? :) Maybe write two simple sentences using these forms to illustrate the meaning :)
