Why do my contacts lenses keep shifting out of place?
JUN 01, 2018
I have astigmatism and my contacts constantly shift out of place, which causes blurry vision. Do all contacts for astigmatism have to be placed in a specific position to avoid this?
Contacts that correct astigmatism float on the tear film on the surface of your eye and should stay in a reasonably centered position during normal wear. It sounds like your contact has an internal curve that is too flat compared to the curve of the front of your eye, causing it to rotate on the tear film too easily. You should return to the eye care professional who prescribed your contact lenses. Perhaps a new lens with a steeper base curve would fix this problem.
