Most eye infections appear to originate from contact lens cases. This paper reiterates the importance of contact lens case care with the following conclusion:
"Contact lens case contamination is a significant public health concern and may contribute significantly to the development of bacterial eye disease in contact lens wearers. Patients should be reminded that they must clean and disinfect their lens cases daily, should avoid the use of tap water for rinsing them, must not top up their solutions, must take into careful consideration where and how the cases are stored during the time that lenses are being worn and that they must be replaced regularly. The adoption of these methods will substantially reduce the levels of contamination of cases with pathogenic microbes."
