Generally speaking, if a criminal suspect is described by witnesses as having a unique physical feature, and that description is correct, it tends to lend credibility to the criminal accusations. Since Otto Moll did have an eye injury, the descriptions of him having a "glass eye" or being named "Cyclops" could be taken as evidence against him.
With this in mind I am checking witness statements. Here is Shlomo Dragon:
The person in charge of Crematoria III [IV] and IV [V] and Bunker 2 was Oberscharführer Moll. Moll was a man of average height, bursting with health. He parted his blond hair to the side. He had a left eye of glass. He was about thirty-seven years old.
We Wept Without Tears: Testimonies of the Jewish Sonderkommando from Auschwitz (2005) by Gideon Greif, p.160
Contrary to Shlomo's claims, it was Moll's right eye that was injured, and Moll would have been from 26-29 years old at the time he was in Auschwitz. Shlomo's brother Avraham, participating in the same interview, did not correct him. Are we sure they met Moll?
None of the other Sonderkommando quoted in this book mentioned Moll's eye. I am having to search far and wide to find any witnesses who did. Here is Filip Müller in 1979:
Moll was rather short and thick-set. His chubby face was, as is often the case with gingery-blond people, covered with freckles. He wore a glass eye. In the Sonderkommando we used to call him ‘Cyclops’.
Three Years In The Gas Chambers (1979) by Filip Müller, p.125

Müller did not say which eye was glass, but at least he said something about it, which makes him superior to other Sonderkommando witnesses in a sense. Müller may be the only witness who ever gave him this nickname of "Cyclops". (I therefore find it strange that Wikipedia's article on Moll calls him by this nickname in the first paragraph.)
Here is another late description:
Although Moll was about forty-five, weighed about 120 kilos, and was of only average height, which was odd for an SS man, he carried himself well. With his broad shoulders and muscular body, he looked youthful. His straight blond hair was cut short. In his chiseled face were set a pair of cold blue eyes. Only one of them was real, for he had lost the other fighting in France. When he spoke, only the live eye shifted. There seemed to be no real feeling in the heart beating beneath his bulging chest. All in all, in his tight uniform and knee-high boots, he looked like a Prussian warrior or the perfect Nazi poster boy.
The Dentist of Auschwitz: A Memoir (1995) by Benjamin Jacobs, p.135
The author Jacobs made the minor mistakes of getting Moll's age and his injury story wrong. Jacobs mentioned Moll's eyes in several other parts of the book but never said which side was which. He described it as a glass eye in one part (p.150). Worth noting that Jacobs described Moll as a much softer figure than he is normally portrayed. He even wrote that Moll rebuked an underling for something done to a Jewish prisoner (p.157).
Finally, Moll's glass eye is mentioned in
this Spiegel article in relation to an interview of an Auschwitz survivor named Esther Bejarano, however, it's not a direct quote. Since this detail doesn't appear in Bejarano's other interviews and appearances, that I can find, I assume it was Spiegel's own editorial addition.
In conclusion: Out of all the witnesses who claimed to know Moll during the war, I can find only four who mentioned his glass eye. Of the four, two claimed his injury was on the wrong side, and the other two did not say which side. Considering the large number of witnesses who had stories about Moll, this is a pretty surprising absence of correct information. People who actually knew Moll ought to have known he had a glass eye on his right side.
Alternately possible is that Moll did not have a glass eye but merely a sightless eye. From the photos and videos above, this seems possible. In that case the absence of remarks about it would be less surprising, but it would also mean the four witnesses lied about it and the historians bought their claims.
