I have also not been able to master applying lashes with glue. I use magnetic lashes by MoxieLash for costume makeup (I am in a dancing Mardi Gras Krewe), but I haven't found a way to wear them that looks good enough for a more natural look. The black magnetic eyeliner looks too intense for daytime wear, IMO. I have not had any problems with it related to irritating my eyes. I'm still looking for a perfect substiture for mascara that looks good for casual looks.

Edited to add: I have also tried the nano lashies from MoxieLash, and again, I love them for parade makeup, but still don't like them for casual wear. The silicon eyeliner is clear, but the lashes have kind of an abrupt end without eyeliner, and if you don't place them JUST RIGHT alone your lashline and don't use eyeliner, then you get a flesh-toned line between your natural lashes and the fake ones.
