So this pretty much means that the Jews are ‘blind’ until they accept Jesus, correct?
If you accept the claims of the New Covenant, yes. They are blind in that they stumbled over the stumbling stone, Jesus. With their cornucopia of blessings the Jews had every warrant to believe on the Son.
But what does the Scripture say? “Look, you scoffers, wonder and perish, for I am going to do something in your days that you would never believe, even if someone told you.” (Acts 13:41, also Habbakuk 1:5)
