Scratchy matter

Once it seems no longer to give my longstanding contact lenses in my strength, I now had to look for a new product and I am - not least because of the many positive customer reviews - landed monthly lenses at the PureVision Spheric.
I have more than 20 years wearing contact lenses, so I am an "old hand" in this business, and I usually have not so super sensitive eyes. In addition to clean my lenses every evening or overnight care. But with these lenses I got nothing but headaches. Only when handling the lenses are little soft, rather rigid, inflexible and somewhat hard.
And the eye scratching! I can not say otherwise - I always had the feeling of having glass splinters in the eye, and I had to constantly blink and rub on the eye in order to defuse this uncomfortable, scratchy feeling which then also with the time blurred vision and streaks all set in front of the eye.
Very annoying, I found every night this Gepule eye until things were fished out again. I had really never, so she was brought little more from the eye contact lenses that have drawn so tightly to the eyeball. As I said, I am a long-time contact lens wearer and have tried many lenses - but these are among the worst with that I've ever had.
I changed shortly after 2 weeks on the glasses - a feast for my eyes, when finally this scratchy plastic things were out - and now wear a very comfortable no-name product that supple my eye adapts, does not scratch, not schliert, allows a clear view and can be removed at night without any problems.
The PureVision monthly disposable lenses, however, were for me, unfortunately, a bad buy, and I have two packages - up to 2 lenses, which I used for 2 weeks - (I have on each eye in each case a different vision and need therefore different lens strengths) unused thrown in the trash. Too bad, but not to change.
