I vaguely remember this novel that I read when I was a teen, and would love if you can help me find it, for some reason I cannot stop thinking about it for the last couple of weeks.
The premise was based on some technology that allows to record everything on different sets of eyes that people use to record and then replay by inserting those eyes in their eye sockets. There was a somewhat far-fetched plot, where a woman lost her eyesight and was forced to use these sets of eyes and would have to decide which sets of eyes (based on their capacity) to use. Then the main hero of the story lost his eyesight as well. I remember that in the end it kind of stopped making sense, because why can't you just use normal (no delay) eyes that show you everything in real-time, was not really that well explained.
It was a novel, by some sci-fi author who was not that popular (at least I haven't heard of him before, though I may be mistaken), and the premise was vaguely noir-ish with the main protagonist a private detective or a policeman. It was written before 1993. The atmosphere was Philip K. Dick-ian in a way.
