Weekly Contact Lense. Now you can experience the extraordinary ease of wearing a new pair of contact lenses every weekly. Only wear them in the morning and throw them away before going to bed. Then, at the beginning of the second day, just insert fresh, new and sterile contact lenses from DAILIES (nelfilcon A). There is no solution, no storage, no lens maintenance issues. If worn correctly, they will provide you with excellent comfort and convenience to successfully wear contact lenses.
