Why Should I throw my lenses away every day?

In this busy world, convenience is king.  So from the stand point of, you the patient, there is nothing more convenient.  But from the doctor stand point, there is nothing more upsetting then a patient suffering with extreme pain from contact lens related infection.  

The studies have shown that patients wearing reusable contact lenses are 12 times more likely to have a serious eye infection then lenses that are disposed of everyday.  

Most of the time we can treat the patients and restore their vision.  But not always.  Is it really worth the risk and the pain and suffering of the patient.  I say no.  Plus even though the lenses cost a little more, whats the cost of loosing a day of work or more.
