Try the first contact lenses that you can barely feel. Total 30 monthly lenses from Alcon have a water content approaching 100% at the surface. Your eyelids glide gently over a cushion of moisture. Thanks to the silicone hydrogel material with 55% water content in the core, Total 30 lenses can be worn for up to 16 hours no problem. These are the first monthly lenses with this water gradient technology and they continuously provide the cornea with adequate oxygen, guaranteeing optimal comfort, day in, day out. In particular, long periods working on screens in our digital daily life are no problem with the Total 30 contact lenses because they have a light blue light filter. The innovative CELLIGENT technology ensures the surface of the contact lens is always moist and protects it against bacteria and fat deposits. The technology mimics the surface of the cornea, ensuring natural moisture retention and a particularly smooth surface, even on day 30. In addition, Total 30 lenses offer Class 1 UV protection, which makes them perfect for all situations in life.
