I hate false eyelashes. They look tacky and cheap. You could try buying mascara that makes your eyelashes look bigger, I know there's a lot of products like that. Just don't use fake eyelashes, my old dance teacher did, and it freaked me out. Oh, to answer your question, it is probably bad for your eyelashes, with the glue and all. I'd say voluminous mascara is a much better choice.
