I have each of the four unusable lenses worn for several days to my hand, exclude any debts and not to dispose of any lens in haste. Thus, I am absolutely sure that my eyesight has not deteriorated abruptly in a magical way and clearly defective goods exists.
I hope Ciba Vision takes the many, resulting in a short time, negative reviews to heart and checks the Produkionskette because I really like the lenses ever worn to the current batch.
