Wearing contact lenses should not hurt, especially when properly fitted and conditions are normal. A contact lens can hurt if you trap dirt or dust between your eye and the contact lens. Take them out and clean them with multi-purpose solution. If the problem does not go away, throw out the contacts and try a fresh pair. Also, if you scratched your cornea at any time, it will hurt when you put in a contact lens. Though frankly, if you’ve scratched your cornea, you’ll probably already know it and will not want to go near your contacts until it has healed. Aside from that, if at any time your contact lenses hurt, you must take them out, and consult with your eye care practitioner.
