If you’ve ever had an eyelash or a piece of grit stuck under your eyelid, you’ll know that it’s one of the least favourite activities known to humankind. So what happens when a contact lens disappears into the depths of your eye? Luckily, not much.
Reassuringly, it’s not possible for a foreign object to go behind your eyeball. That’s because a thin but tough membrane called the conjunctiva forms a lining inside your eyelids and then curves around, covering the white of the eye.
So the worst that’s likely to happen is that your contact lens can slide around, becoming misplaced under an eyelid. To remedy this, roll your eyes in the direction of the lens, which will probably slide it back to where it should be.
Soft contact lenses tend to centre themselves automatically on the cornea, but RGP (rigid gas permeable lenses) may need to be manipulated with gentle finger pressure on the eyelid.
