If you're looking for contact lenses that you can just forget about, you are in the right place. Extended wear contact lenses, also known as continuous wear contacts are meant to be worn for long periods of time, including night time, while sleeping. They are made of highly breathable materials, mostly silicone hydrogels, which allow the oxygen to reach the eye even when you're sleeping. Due to this feature, they are recommended mostly for people who work night shifts, lead irregular lifestyle or simply often forget to take their lenses out. Make sure you read the manufacturer's guidelines as far as extended wear contact lens use, as all brands recommend different usage time. We also suggest asking your eye doctor for advice on that matter.
