Even though the lens is completely opaque, you can see
well because the center of the lens is clear. The only
vision problem you might notice that your peripheral vision
is not as good while wearing crazy contacts.
If you normally wear glasses of prescription contact
lenses, you can get Crazy
colored lenses with corrective power. So your eyes
would look crazy, but still see well.
If you have perfect vision, then you should go for plano
(zero correction) crazy contacts.
Crazy contacts are comfortable – as comfortable
as costume lenses can be. But you can’t wear them
for longer then 8 hours. Which is a long time if you wear
them as Halloween crazy
They are simple to look after. Just wash them in the
solution before insertion. If you leave your Crazy lenses
in the solution for a few weeks, it is recommended to
change the solution from time to time. And give them a
very good rub and rinse in a new solution before putting
them in. Your can use them only once a year or every day,
it doesn't affect the quality of your lens.
