amateur astronomer, then you must pluck out your eyelashes so as not to have them interfere with your eyepieces. This will avoid all those nasty oily smears on your $400+ eyepieces. Eyelashes don't seem to support any useful function anyhow...
I don't recommend that you use scissors unless you have very steady hands - you could jab them in your eye unintentionally. The use of hair removal cream is also not advisable, since they are caustic. If you mainly use eyepieces with small exit pupils you may get away with just removing the lashes in the centre portion of your eye(s) - dunno what style you would call this, but it's like the opposite of a 'Brazilian'.
Unless you are really making a statement, you might wish to apply this treatment to both eyes equally, since otherwise you may scare small children or less enlightened astronomers. You will still look weird, but it's a small price to pay for the warm glow you will get for taking this hobby seriously....
