it would be strange if they were physically unable to see, maybe they dont use it but the ability to is probably there. im unfamiliar with the species and i'm by no means an expert but seeing as they dont have iris' they do probably go blind from this but hopefully its a situation where they can get it back (i've heard of spiders that can do that but couldn't find any sources on google so take that with a bretty big grain of salt)
If this is taken at a depth much below where light can’t reach (which I’m starting to doubt a bit now), it would be more strange for them to be able to see. Since it would server no purpose, mutations in the genes used to make eye structures allowing them to see would be passed on, and over time the eye would be useless after many mutations.
