Special effect contacts are great for
Halloween and also for the people, wishing to give their
appearance a touch of extravagant.
CIBA Vision produces Wild
Eyes colored lenses in white-out,
contacts, wildfire, red-hot, ice fire, hypnotica,
knockout, zombie and alien. Cooper Vision produces Crazy
lenses with designs of cats eye, Red spiral, Wolf,
White eyes, Black spiral and Flame.
However, crazy lenses present
some risks to their wearers. First their oxygen permeability
is very low, due to a thick layer of color. For this reason
you shouldn’t wear them for long, hours –
3-4 hours at best.
According to manufacturers, you can wear your lenses
all day, but most eye doctors don’t recommend doing
that. Also you should never share your lenses with other
people, it is a sure way to get a nasty eye infection.
Driving in Crazy
contact lenses might present additional dangers. Even
though the center of the lens is clear, under low light
conditions, when your pupil becomes larger, lens might
cover part of the pupil. Be sure you can see well in the
dark, before you drive at night wearing Wild Eyes.
