Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses. Has any active* ocular pathology or severe insufficiency of lacrimal secretion (moderate to severe dry eyes) that would affect the wearing of contact lenses. How these materials perform in terms of lens deposition, particularly lipid that silicone hydrogel lenses are prone to, will be interesting, particularly with recent correlations between laboratory analysis and clinical findings. For the first fifty years, glass was the only material used.
