these lenses are perfect. I bought them for Halloween and have had an effect, everyone was impressed by them. Delivery was fast because I was afraid not to receive on time but they are arriving on schedule. The application is very simple because I, who had never previously set lenses have only 5 minutes to put them. It took me some time to adapt (cast my eye, and vision), but after 3 minutes AC was better. We see perfectly well with. It is on that I will redeem others.
