below in case there's anything I forget so if you're anybody like me you love
contact lenses and colored contact lenses are some of the coolest that are
out there and again if you like me you like also dressing up for different
parties whether it's Halloween maybe a Renaissance Festival or going to an
event like Comic Con but when it comes to wearing colored contacts there is
some information that most people do not know about them unless you in the eye
care business like myself and there's a few things I want you to know and they
just might save your eyes and prevent blindness tip number one is to pay
attention to how long you are wearing these types of colored contacts
one thing that most people don't know about contact lenses is that they
actually do have to let oxygen pass through the plastic on the eye the
surface of your eye has to actually breathe oxygen and if for some reason
something is blocking that flow of oxygen to the cornea it can cause a lot
of complications and even lead to damage of the eye now most of the modern
contact lenses that are out today have a really good oxygen flow through that
type of plastic however most of the cosplay contact lenses and circle lenses
that you find on the market no matter where you're buying them from they're
usually not new material they're very old material actually dating back to the
1960s and actually was until the 1980s that scientists found that there's a
minimum level of oxygen that needs to pass through the plastic of a contact
lens to get to the surface of the eye to prevent hypoxia and damage to the eyes
surface the most common material for a cosplay or circle lens to be made out of
is a material called polymacan and you can usually tell what the material is
made of those lenses even if they don't tell you because it'll say a water
content of 38 percent if you find a site that is
selling colored contact lenses like these and they say that they have a 38%
water content and they expire in 12 months I can almost guarantee you they
are made of polymacan and polymacan has a very low breathability for the
surface of the eye so low that you're almost guaranteed to have some level of
corneal hypoxia now oxygen flow to the cornea can be somewhat adequate if the
lenses are fitting correctly that means that there is actually flow of tears
going behind that lens so make sure that talk with your eye doctor about getting
these fit properly but by watching the amount of hours that you wear these
contact lenses and reducing those hours down you're gonna reduce the chances of
you having any sort of corneal hypoxia and other complications and certainly
please don't ever fall asleep wearing these lenses they are not approved for
overnight wear tip number two is that wherever you are buying your contacts
whether it's from an optical or an online retailer that you buy from a
trusted place just recently the BBC actually reported fake contact lenses
being sold through online retailers so when you buy these contact lenses from
really sketchy websites that are often selling them at a price that's like too
good to be true you really have to start to question is this something you want
to be putting in your eye it's actually found a lot of lenses being sold that
we're not sterile meaning that the lens is straight out of
the pack could have actually been harboring a lot of nasty bacteria that
could actually cause just some of the most awful eye infections possible and
infections from contact lenses can lead to some of the nastiest problems with
the eyes and even lead to permanent vision loss
so again wherever you're buying them from make sure that it is a trusted
source also make sure that your prescription for these lenses are
up-to-date here in the United States contact lenses are regulated by the FDA
as a medical device and any website or person who sells them to you without a
prescription is breaking the law and it's not in your best interest to get
those lenses anyway because they won't be specifically made for your eye and
you won't know if they're actually healthy for you tip number three is just
hey be smart and be safe whether you're going to an event you go into a
comic-con you go into a Halloween party and you learn these cool colored lenses
just if you're having any problems at all the eyes are getting
painful visions getting blurry take out those contacts right away and give them
a break and make sure to bring your glasses along just in case you do have
any sort of problems and if you're experiencing problems with your eyes
make sure do talk with your eye doctor you do not want to postpone treatment if
you do develop an ulcer or an infection from wearing colored contacts please
contact your doctor right away I don't want anything bad to happen to you or
your eyes remember that you only get two eyes so please take care of them so I
