Morphology

miosis = mio (opaque) = mio + sis

The immediate base 'mio' is not a standalone English word and its meaning is not transparent to most learners.

Etymology

Miosis comes from the Greek root mei- meaning 'less' or 'to make smaller', so it literally means 'getting smaller'. That's why miosis is used for the pupil shrinking in bright light.
