Applying contact lenses is a lot more work than getting them out again. With the Contact Lense Sprayer, the lens gets built right on your eye.
Precision spraying aparatus applies material of the right thickness and contour to act as a contact lense. Every time you use it, it takes an instant prescription
check (matching up with your medical records by scanning your eye), and works out the most perfect lens shape to build.
You could even take a portable model with you. If your lens falls out in the street, don't bother picking it up or blindly staggering your way home. Just take the lens sprayer out of your bag and apply a new one. At the end of the day, the lenses are easily disposable, and you don't need to worry about carefully storing them.
I realise that this would require inhuman levels of precision. I realise that it would be prohibitively expensive. I realise it would never work. But isn't that what the halfbakery's for?

Not in my experience. I have no problem inserting lenses, but if my eyes have dried out somewhat throughout the day, or the lenses slip around, can be more difficult to remove. |

Maybe i have very wet eyes. I always had all sorts of problems with lenses that wouldn't stay in place. |
|

The spray on contact lens machine tickles a bit when it sprays the lens. I quite like the feeling. The eye clamps I need to hold my eye still while I'm using it are a different matter though. |
|
| |
Perhaps it could start by spraying on a little anaesthetic or muscle relaxant? |
|
| |
Yes - especially as I can't get normal disposable contacts (I have an astigmatism).. |
|
| |
This is actually a cool idea... when I had contacts my
problem was always getting a cat hair between the
contact lens and my eye. (ouch!) Perhaps this device
could blow a bit of air on the eye before blowing the
actual contact lens to remove the obligatory cat hair cat
owners seem to have. |

They already have contact lens drops - how does a spray improve on this? (I would have thought it much easier to deliver the quantities necessary using droplets than a spray.) (FJ: yes, I do mean what I say; can't find any links, tho. I'll keep looking.) |

DrCurry: Shirley you mean drops of lubricant or a liquid to sooth irritation, not drops that become contact lenses? |
|
| |
I would spray twice to get telescopic vision. |

I need more information (e.g. material used; how shape is determined, and actually formed; what keeps this adhered to the eye without sticking to it; how the material solidifies and does not turn runny under the lid; how a spray material that solidifies could be completely transparent and error-free... things like that). It seems impossible to me on first read. Without more detail, this is essentially a WIBNI. |

dammit - what a morning. First I brush my teeth with my wife's suppository cream, then I spray my contact lenses on but use quick drying enamel paint instead. If only I didn't need the darn things in the first place, then I could pick out the right can. What else can possibly go wrong? (falls over dog and down stairs, cuddumph). |

Always a pleasure, bliss. |
