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.
