At night, my eyes are so dry that my contacts are literally stuck on my eye. What can I do to safely remove the lenses?

Dry Eyes and Contact. The best solution for your problem is to treat the dry eye condition. You may want to discuss various treatment options with your eye care provider. Also, in the short term, a lubricating eye drop or rewetting drop, may lubricate the eye enough to make removal of the contact lens easier.
Artificial tear. Let the tear soak in, hydrate the lens, move the lens downward off the cornea and then pinch to remove. Don't wear as many hours and keep eye lubricated.
