I ordered these contact lenses for Halloween. On the Internet you can find some tutorials on how you deal with these big lenses. This helps in some way. The lens cover 22mm of the eye, so that in most cases the whole eye is black. Depending on the light in his eyes, however, the iris to see. I myself have brown eyes, because that falls on not so. In dark rooms one sees then already nothing left of the iris because the pupil is so extremely expands, that even the edge of the lens in the picture while wearing the lenses. Unfortunately, that's inserting difficult, but after the 10th time goes also. The eyes are at the beginning rather irritated because the edge of the lens is located in the song section. This is unusual, however. With additional drops that moisten the eye bearable, and after 30 minutes no longer disturbing. However, what bothers me, you can see by the increased lacrimation running after, everything blurred. This also takes about 15 minutes. to the sets. Then you can go to any 3rd blink see clearly, otherwise it remains blurred. That is also the reason for the few stars. Either it's up to my eyes, but work with other contact lenses or the lenses are simply too big and moved the blink and pull air, so that one thus looks blurry.
