Can my contact lens slip behind my eyeball?
This will never happen. They can only move on the white part of the eye. You just need to re-center the lens by moving it gently.
I have a prescription for gas-permeable lenses. When do I need to do to renew it?
All our gas permeable lenses must be renewed at least every two years.
What should I do in case of discomfort or pain?
Your lens is sending you a sign to say stop wearing them. You should remove your lenses and contact your eye care professional.
