How can i out eyedrops into my own eye? i keep missing?!

Instead of tipping your head back and aiming blindly for your eye, try this:

Look into a mirror and pull down the skin of your eyelid on the lower outside corner, farthest from your nose. The lower lid should pull away from your eyeball and there is a little open area, almost like a tiny "pouch" between the skin and eyeball. Without touching the tip of the eyedrop bottle to your skin or eyeball, drip the eyedrop into this little "pouch." Tilt your head back slightly, and close your eyes for about five seconds. Then open your eyes and blink rapidly a few times. The blinking ensures that your lids wash the drops over the entire surface of your eye.

Are you trying to say "how do you put eye drops in your eyes?" You pull down your lower lid, place the dropper or eye drop bottle near the inside corner of your eye, without actually touching your eye, look up, and squeeze the bottle, then blink. Hopefully, the drops will go into your eye. Use a clean tissue to blot the excess spillover of drops. A small amount of eye drops will almost always spill out of the eye, even when inserted by a medical professional.
