How can you tell if you have been fitted wrong for contacts? I have colored contacts and i can't keep them on my corneas. I can literally watch them slide down my eyes. When i blink they go back up, but my sight is blue and blurry. When i move them back to where they need to be they just slide right back down. My eyes are not watery,as i have overcome the eye touching part. Any advice would be greatly appreciated. Thanks!
