I'm pretty sure it serves as an artistic symbolism. The only cover I can recall that hints this would be of Tokyo Ghoul vol. 13, the one that features Arima. Under the blood splattered marking of his right lens there is a vague neon-ish yellow hue emitting from his eye. This connects a lot of theories going around about Arima, it seems to emphasize the speculative importance about his right eye. I won't go indepth, but there is a lot to take note of about such a slight detail.
