Air Optix coloured contact lenses are breathable contact lenses that provide outstanding comfort and stunning colour. Each box includes two monthly lenses. Suitable for daily wear, these lenses should be removed prior to sleep, but can be reused for up to 30 days. Air Optix Colours are made using SmartShield® Technology, which creates an ultra-thin protective layer. This helps shield your lenses from unwanted deposits, and provides consistent comfort in every wear. Lenses only available in an 8.6 base curve and 14.2 diameter.
