it also depends on eye colour sometimes....for some reason visine works better on blue eyes but then again that could just be the contrast is less.
lol Rhoto V Arctic , Opcon-A , Naphcon-A These 3 drops are the best any rhoto will do to Arctic is just my favorite
Personally, I prefer clear eyes. Visine seems to make your eyes noticeably extra white while clear eyes just gets rid of the redness.
