How does the contact lens stay in the center of the eye and not go anywhere in the white part when already worn?
In: Biology
A few other commenters have already remarked on the horror stories of contacts being trapped under the lids or at the side of the eyes and that the contacts are designed to center themselves on the cornea. I’d just like to add (as a regular contact wearer myself) that basically every time that you blink you are correcting the position of the lens and re-centering it. It’s partly just your natural blink and partly a learned but now autonomic blink.
Occasionally – especially if your eyes get too dry or too teary – your lens will drift off to one side and you’ll need to assist it back into place with your finger – if it persists take it out, rinse it in solution and put it back in after letting the eye calm down.
