FreshLook Colors (2 lenses) – dioptric. Monthly, coloured, vision corrective contact lenses that significantly change the colour of your iris. FreshLook Colors are available in blue, green, hazel, violet, sapphire blue and misty grey. These contact lenses have an inside-out indicator (letters or numbers), which is visible on the lenses and provide an easier handling. The UV filter in contact lenses increases the protection of the cornea from the dangerous ultraviolet radiation. However, lenses do not cover the entire eye or eye area, so the combination of contact lenses that have UV filter and sunglasses is the ideal protection against harmful UV rays.
