"Bandage up me eye with me own history/ Blind me to me own identity"
Metaphor to compare the British education system to a bandage. The typical purpose of a bandage is to cover a wound- prevent the wound from becoming infected and speed up the healing process.
"Blind me"- an inability to see. In this case, Agard compares the education system to a bandage in order to show us how they pretend to be teaching us the most important history which is the most beneficial to us.
