If the eye glasses are not the right size type, they will not fit when you carry them. You will need to go to a store or optician to have them re-worn. If it is not due to the model, there may be a problem with the way you wear them. Generally, when wearing contact lenses, you have to wash your hands clean, then turn your eyelids up with your left hand, sometimes use tweezers to take the contact lenses out of the case, gently let it combine with the pupil want, and the contact lenses are put on. After putting them on, you have to close your eyes for four seconds to see if there is any discomfort. If there is no eye discomfort, the process of wearing contact lenses is complete.
