I don't think caring a small mount of contact solution is silly,for you It's just a part of maintaining your hike.Mine would be some meds and inhaler.I too carry small polycarbonate mirrors,for tick removal,shaving,and in case I have to get my picture took,LOL for me wear reading glasses is a must If I want any shot at reading a map or compass,or seeing what little small things,wonderments a body can find on the trail ie;rocks,minerals,flora and fauna.
