Verily, Allah is not one-eyed but Al-Masih Ad-Dajjal is blind in the right eye which looks like a swollen grape

1819 - وعن ابن عمر رضي الله عنهما أن رسول الله صلى الله عليه و سلم ذكر الدجال بين ظهراني الناس فقال : [ إن الله ليس بأعور ألا إن المسيح الدجال أعور العين اليمنى كأن عينه عنبة طافية ] رواه الترمذي

`Abdullah bin `Umar (May Allah be pleased with them) said: One day the Messenger of Allah (PBUH) mentioned Al-Masih Dajjal (the Antichrist) in the presence of the people and said,
"Verily, Allah is not one-eyed but Al-Masih Ad-Dajjal is blind in the right eye which looks like a swollen grape.''[Al-Bukhari and Muslim]
Commentary:
All these narrations about the mischief of Dajjal are correct and have been narrated through reliable narrators, and all scholars agree on their being true. They have been reported by Al-Bukhari and Muslim, whose narrations are unanimously accepted by the `Ulama'.
The second coming of the Prophet 'Isa (Jesus) from the heavens is proved on the basis of such reliable and true narrations that none can contradict them. Before the Day of Resurrection all these things will happen, and it is essential to believe in them.
Dajjal would be a descendant of the Jews, and he will be called Dajjal because of his mischief. The meaning of Dajjal is `one who greatly resorts to fraud and deception'.
Allah will also give him some extraordinary powers to test the belief of the Muslims. Dajjal will claim to be the lord of the world. A large portion of the Jews will be with him. He has also been named as Al-Masih Ad-Dajjal in some narrations. Jesus, son of Mary (Peace be upon them) will have the honour of killing him.
