His eyes are blinded from seeing/ "his eyes are bleary (misty) tritutable"/ grindable
He did not see things he should have seen. He does not understand what is happening, as if his eyes were covered with plaster.
("They knew not, neither did they understand, for their eyes were blinded from seeing, their hearts from understanding" - Isaiah 44:18; and: "And she answered in the heat of her spirit and said, 'Are your eyes blinded from seeing?'" - S. Y. Agnon / In the Prime of Her Life)

טַחוּ עֵינָיו מֵרְאוֹת
Definition (Hebrew)
לֹא רָאָה דְּבָרִים שֶׁהָיָה עָלָיו לִרְאוֹת. לֹא מֵבִין מָה שֶׁמִּתְרַחֵשׁ. כְּאִילּוּ עֵינָיו מְכֻוסּוֹת בְּטִיחַ.
("לֹא יָדְעוּ וְלֹא יָבִינוּ כִּי טַח מֵרְאוֹת עֵינֵיהֶם מֵהַשְׂכִּיל לִבֹּתָם"- יְשַׁעְיָהוּ מַד יח, וְכֵן:"וְתַעַן בַּחֲמַת רוּחָהּ וַתֹּאמֶר, הַאִם טַחוּ עֵינֶיךָ מֵרְאוֹת ?"- שַׁ"י עַגְנוֹן/ בִּדְמֵי יָמֶיהָ)
