There are several explanations scholars of Tafsir have stated:
1- As you said, they would be resurrected blind but then later they would be given eyesight to see the punishment of Hell or other stations of the Day of Judgment.
2- They would be blind from seeing the path of salvation there. They would be lost, without light, not knowing where to go.
3- They would be bling from seeing certain realities, but they could see other realities like their book of deeds or punishment.
