for the left, make sure it is a bit moistened with some of the saline stuff. Try to keep the lens open, tuck it into the lower lid and then try to squish it (gently) against your eyeball. Blink around a few times. Use a mirror (definitley). I have had contacts for 10 years and I still need a mirror!
Sorry to say, but you have to practice, practice, practice.
Hang in there...you'll get it!!!
