Soft lenses also come as disposable products, that is, used once and discarded, or as planned-replacement lenses. Extended wear touch lenses are used for overnight or continuous wear fluctuating from one to six nights or up to 30 days. Soft touch lenses are made of soft, flexible plastics that allow for oxygen to pass through to the cornea.
There are two general categories of touch lenses - soft and rigid gas permeable. The length of continuous lens wear depends on the lens type and your doctor's assessment of your tolerance for overnight wear. Some doctors prescription disposables as planned-replacement lenses, which are removed, disinfected, and reused before being discarded.
