For the Love of your eyes, Please change your contacts! We just read an article about a college student who lost your vision because she did not change her lenses for 6 months. A parasite got under her contacts and ate her corneas away. Yes a single cell Amoeba called Acanthamoeba caused her to go blind! All she had to do was simply clean or disinfect her contacts and the microscopic critter would have been gone! So sad. Contacts are only a few dollars each. A cup of coffee. Its a terrible tragedy, however it would have never happened if she took proper care of her contacts.
