Sweety Firefly blue are exceptionally opaque. They cover brown eyes dramatically. Carrying a vivid pattern and an over emphasized limbal ring, these lenses do great at creating an illusion of bigger & bold eyes. The strong pigmentation sets them perfect for cosplay too.

 The diameter is quite big but the lenses are still really comfortable, my eyes feel totally ok after wearing them ’cause Sweety is an amazing brand and even it’s bigger lenses are really comfy! – source
