i'm sorry to hear you've lost a contact lens in your eye. it's not as uncommon as you might think! the good news is it's impossible for a contact lens to actually get behind your eye. usually what happens when a soft contact lens magically disappears is it gets dislodged from the cornea and stuck under the upper eyelid. sometimes a soft lens can get folded in half so when you eventually find it it may look distorted. you can usually get the lens unstuck by put some wetting solution into your eye and blinking rapidly several time to bring the lens into view. if that doesn't work try adding more wetting solution and gently turning your upper eyelid inside-out. this can "pop" the lens away from the upper lid. if none of these solutions work you can always call your eye care professional for more advice or even an exam to find that darn contact lens and get it out! hope this helps!
