New generation of well known and trusted brand of contact lenses Biomedics 55 from CooperVision, also known as Mediflex 55. Due to their spherical aberration, these monthly contact lenses provide clear, crisp and sharp vision, regardless of the amount of correction required. Biomedics 55 can also correct low values of astigmatism and their rounded edge design provides excellent comfort. Great value, low price lenses. 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.
