2 weekly lenses are soft contact lenses that can be worn for 2 weeks. They are worn during the day and stored in a lens container with lens solution at night. For most lenses, the lenses can either be worn day and night for 1 week or can be changed every 2 weeks when the lenses are taken out at night. Here you can (if the eye is suitable) choose how you wear the lenses.
Hygienic and correct use is very important for eye health.
