Practice makes perfect! I've been wearing them for almost 4 years now, and I think it takes a couple of months to get used to them. Basically, I've found that the easiest way to get them in is as follows:
-turn the lense so that there isn't a 'lip' around the top (if you flip it both ways it should become apparent what I mean!) and put it on your middle finger of your left hand, if you're putting the lense in your left eye, or the opposite for your right eye.
-bring your other arm over your head and use your hand to pull your top eye lid up
-use your index finger of the hand with the lense on to pull your lower lid down, and then look directly at your middle finger as you bring the lense towards your eye.
-blink slowly, and move your hand away from your eye.
With practice, you'll get the hang of it eventually so don't give up just yet.
