The Antichrist will be spiritually blind

عَنْ أَنَسٍ، رضى الله عنه قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم: مَا بُعِثَ نَبِيٌّ إِلاَّ أَنْذَرَ أُمَّتَهُ الأَعْوَرَ الْكَذَّابَ، أَلاَ إِنَّهُ أَعْوَرُ، وَإِنَّ رَبَّكُمْ لَيْسَ بِأَعْوَرَ، وَإِنَّ بَيْنَ عَيْنَيْهِ مَكْتُوبٌ كَافِرٌ‏‏.

It is narrated by Hazrat Abu Anas^ra that, “The Prophet^sa said, ‘No prophet was sent but that he warned his followers against the one-eyed liar (Ad-Dajjal). Beware! He is blind in one eye, and your Lord is not so, and there will be written between his eyes ‘kafir’ (i.e., disbeliever).”
