Firstly we must remember no matter what type of Color Contact Lens you going to purchase and use, no matter how long you going to wear it and no matter from who you are buying it, “ALWAYS REMEMBER THIS IS A MEDICAL DEVICE EVEN IF IT ISN’T FOR CORRECTIONAL VISION PURPOSES, AND IS PUT ONTO ONE OF THE MOST SENSITIVE AND VALUABLE BODY PARTS, YOUR EYEBALL AND MOST VALUABLE SENSE, YOUR SIGHT”
So that being said remember always contact a medical professional first before you purchase pair of lenses no matter where you get it from as there are many things to consider when using a lens.
