well.. after a few tries and you can put it on, better wear glasses for that day because you eye will tears a lot and swollen. Wait till your eye relaxed then try again.

Not much skill needed actually, hold it with 1 finger, use the other hand to spread your eye open a lil, slide it in either from upwards or downwards, this will overcome when you say that your eye is smaller.

I used to wear contact lenses alot. Now no more.
