It
is very common for new or long term contact lens wearers  to experience
dry eyes when first inserting the lenses ore even blurry vision. This is
because your eye is getting used to the light coming through the lens and
having something over your cornea. You can use Eye Drops (currently not
available here, but soon from September) add one or two drops to your eyes
with the lenses, and blink a few times to spread the solution over the eyes.
This can really make a difference.
