Solotica's Hidrocor Rio Collection introduces four stunning colors to choose from: Buzios, Copacabana, Ipanema, and Parati. The Hidrocor Rio collection from Solotica is pushing the boundary of what colored contact lenses can achieve. The colors are inspired by the natural beauty of Rio de Janeiro in Brazil. Each of the colors has its own story and portraits from the rich forest green to the luminous sky across Rio. Their subtle patterns of this collection have a high opacity and cover the iris fully and completely change the eye color. These lenses are yearly so they can be worn for up to 12 months.
