I love the lenses and they are very comfortable. I used them all day when I was as Rengoku at Comic-Con. I didn't have any vision impediment or other adverse effects.
I highly recommend it.
Lentilles confortables, bien bleue comme sur l'image. Elles ressortent plutÎt bien sur mes yeux (j'ai les yeux bleus/gris). La couleur serait plus visible sur des yeux foncés je pense. J'ai les yeux assez sensibles donc elles sont confortables, je ne les sens vraiment pas !
I wear them all day, at work or just out and about. They're very comfortable and they look so bright. My eyes are naturally brown and they don't show through.
