GEO Crazy Halloween SF14 are perfect deep bright blue contact lenses. They are 100% opaque with natural enlargement of 14.2 mm. Opaque lenses with bigger diameters may sometimes blur your vision; therefore you will find crazy lenses often with minimal to no enlargement. GEO SF14 are intense blue that make your eyes look panicky and outrageous. GEO SF14 crazy lenses have a simple pattern but due to the sharpness and strong pigmentation they make your eyes stand out.
