Question: Among the superheroes with height from 170 to 190, list the names of the superheroes with no eye color.
Evidence: height from 170 to 190 refers to height_cm BETWEEN 170 AND 190; no eye color refers to colour = 'No Colour'

SQL:
SELECT DISTINCT T1.superhero_name FROM superhero AS T1 INNER JOIN colour AS T2 ON T1.eye_colour_id = T2.id WHERE T1.height_cm BETWEEN 170 AND 190 AND T2.colour = 'No Colour'
