Daily Disposable Lenses
You can’t go wrong with disposable contacts. For some people, the sheer convenience of daily disposables is enough to convince them to switch. On the other hand, some people, especially those who suffer from astigmatism, are better off with more conventional disposable contacts. What are conventional disposables? They are slightly thicker versions of the daily contact. They are designed to be worn -- and cleaned -- for two-week intervals -- sometimes longer, sometimes less.
How long you can keep disposable contacts and how often you need to replace them is a matter to discuss with your eye care professional. Some optometrists may suggest you dispose of them every week, some every month -- it all depends on the particulars of your eyes and your level of comfort. Regardless, both daily and conventional disposables tend to be more comfortable choices for people who suffer from dry eye syndrome or persistent eye irritation. The relative thinness of daily disposable lenses makes them extremely gas-permeable and comfortable.
