Finally I made my first review about circle lenses!! I'm addicted to them, expecially because they're essential in cosplaying!
These ones are from Uniqso, first of all I totally recommend this shop because they have a great variety of lenses, you can see the real photos of them from the buyers and their conditions are always excellent.
I bought this pair for my Dawn's cosplay and I'm happy with the results, here's some photos of how they look on my eyes:
(eyes on natural light without lenses on)
(here you can see the enlargement with a comparison)
(both lenses with natural light)
(both lenses with flash on)
and in this last photo you can see the final effect on a cosplay, with makeup on and without light (photo by Chris Zeta).
