Radak

ה' פוקח עורים. "The Lord opens the eyes of the blind": Those who are blind from an eye disease, He will heal them. This ailment is mentioned because blindness, like imprisonment, prevents a person from moving from their place. Alternatively, it can mean those blinded by extreme distress, as suffering is likened to darkness and salvation to light. There are many verses in Scripture that attest to this. Similarly, He did for Israel, who were blinded in exile, as it is said, "We grope for the wall like the blind, and we grope as if we had no eyes; we stumble at noonday as in the night." ה' זוקף כפופים. "The Lord raises those who are bowed down":, meaning the poor, as we have explained. ה' אהב צדיקים."The Lord loves the righteous":, and similarly, He loved Israel who were righteous among the nations.
