Geolica Holicat Funky Cat blue circle lenses are 14.5mm yet the enlargement effect is very pronounced due to the solidly thick limbal ring. These blue circle lenses are neither very bright nor very dull- they are just the right amount of pigmentation that help your eyes being noticed. These lenses even look greyish blue sometimes and may even appear blackish blue- credit goes to the beautiful integration of the multiple hues!
