The phrase "more squint-eyed" can be replaced with several different synonyms depending on the context. For example, it could be said that a person is more "cross-eyed" or "strabismic" if they have a pronounced inward or outward eye turn. Alternatively, they might be described as "nearsighted" or "myopic" if they have difficulty seeing objects in the distance. "Astigmatic" could be used if the person's vision is distorted due to an irregularly shaped cornea. Finally, "squinty" can be used more broadly to refer to the person's facial expression, implying that they have narrow eyes or appear distrustful.
