Cat lenses: It’s all fun, until you can’t see…

Nifty cat lenses could look great with your costume this Halloween. But ask yourself one question: Can you afford to lose your vision for eight weeks or so?

That is what happened to one woman, according to the American Academy of Ophthalmology.

The AAO reports that the West Virginia woman wore illegally made, colored lenses for 10 hours. The lens stuck like a suction cup to her eyeball. She required four weeks to recover from the pain associated with the damage to her cornea and infection. She could not see well enough to drive for eight weeks.

She now lives with a scar on her cornea, a drooping eyelid and vision damage — a bad trade for one night out.

Because of incidents like this, it is illegal to sell costume contact lenses without a prescription. But some unscrupulous vendors do exist.

No contact lenses are ‘one size fits all.’ Your eye must be measured and the proper lens prescribed, or you risk infection, vision damage and more.
