Biweekly contact lenses are intended to be worn daily and replaced
every 14 days. They are a suitable option for people who may experience
discomfort in the last weeks of wearing monthly contact lenses. Biweekly contacts
offer several distinct benefits: more economic, hygienic, and better handling.
One difference between biweekly and daily contact lenses is that biweeklies can be
cheaper and more cost-effective than daily lenses. They are a happy medium; not
only are they more hygienic than monthly contact lenses, they are also easier to
handle than thinner daily contact lenses. Some biweekly lenses are approved by
the manufacturer for extended wear. Wearing biweekly contact lenses longer than
your optician’s guidelines is not recommended.
