Though it may be pretty cool to wear decorative contact lenses as part of a costume, to show support for your favorite sports team or just for something different, there can be some serious risks associated with non-prescription contact lenses. There are a host of problems that wearing these unregulated lenses can cause.
The biggest problem with unregulated colored contacts is that folks who do not normally wear contact lenses do not know how to properly care for them. Because of this, they may not be cleaned correctly, and when this happens, dirt and germs get in the eye when the lenses are inserted. This can cause some pretty severe infections, and if even microscopic particles get between the contacts and your eye, they can scratch the surface of your eye. It is not unheard of for people to have severe damage to the cornea which can cause pain and even blindness.
There is also an issue with the legality of non-prescribed contact lenses. As of 2005, it is illegal for anyone to sell contact lenses to a customer without a prescription. This hasn’t stopped greedy retailers from continuing to offer them for sale however. They are also available online, but they have been made illegal for a reason.
If you want to wear colored contacts, the only way you should go about getting the product is to see an optometrist and get an actual prescription. You do not need to have corrective lenses; the eye doctor will just want to make sure that you will be fitted with a pair that will correctly fit your eye. This will also allow you to eliminate the possibility of getting an improperly manufactured pair from an unlicensed seller that could cause you pain and even blindness.
