👀 目 eye + 争 zhēng (struggle/contend) = the eye-verb that sounds like 争: to open the eyes
睁 pairs the radical 目 (eye) on the left with 争 zhēng on the right, which supplies the sound. So it means specifically to open the eyes, as in 睁开眼睛. The 争 component is the same zhēng you meet in 斗争 (struggle).
睁 — eye radical 目 + 争 (zhēng, contend)
睁 is a semantic-phonetic compound. The eye radical 目 gives the meaning, since the character refers to opening the eyes, while 争 (to contend, struggle) supplies the sound zhēng. It is a relatively late character used specifically for the act of opening one's eyes wide.
