Verdict
The clearest difference is ads: OptiLibrary at none against Eye blink detection's shown. OptiLibrary also leads on device support (3 vs 1) and iOS requirement (11.0 vs 17.7.2). Eye blink detection's advantage is update cadence (every 2 weeks vs monthly). On price and in-app purchases there is nothing between them.
