(Thanks for that one, [World].)
There are specialised materials around that can come into contact with the eye without causing irritation. Contact lenses are made out of such material, for example. A pair of tweezers tipped with such a substance might help get this damn eyelash out of my eye.

"Step 1: poke in eye" With a product like that you'll need a full time staff of product liability lawyers. On the other hand, I can think of few HB ideas that wouldn't. |

Contact lenses do cause irritation to the eye, the eye just becomes desensitised over the course of a few days to the presence of a foreign body. Used as a once-off like this, the tweezers would have no appreciable benefit comfort-wise. The specialised materials that contact lenses are made from are nothing more than oxygen-permeable plastics or silicone-hydrogels, like omafilcon-A or balafilcon, for example. |

Wet fingers don't seem to work for me. Eye baths are good, though. |

I thought that (soft) contact lenses are made out of a polymer that attracts the protiens in the fluid on the surface of the eyeball, so they sort of bond to the eye. Having never worn them, I can't say. |

I think I remember a story about perspex pilots goggles shattering frequently, and the pieces were found not to cause much irritation. Somehow, this led to contact lenses. |

[Detly], the bonding of tear-film proteins to the lens material is the biggest problem facing contact lens manufacturers at the moment....if it wasn't for this issue, contacts could be worn indefinately. It's a drawback, and certainly not the mechanism by which the lenses stay on the eye. |

The perspex-in-eye story is true, but it led to the invention of intraocular lenses (used in cataract extraction surgery), not contact lenses. |

Perhaps they could simply stick iron filings to each hair. If any fall in your eyes, hold a strong magnet to your eye and it will fly out! |

Don't use tweezers -- the premise of your idea is contact lense comfort. A contact lense could be designed to collect foreign objects in the eye. "Pac Man" [link] might be a suitable shape. |

What? Like the inside of the eyelid? Tweezers tiped with the inside of pig eyelids should do the trick. |
