hey, ive just posted a question about these pair of plastic glasses with pin pricks on them which is supposed to improve my vision. Judy B convinced me that this was a scam. But i just wanted to know,HOW DOES THIS PIN PRICK THING WORK? when i put it on, i can see things clearly, but of course not when i take it off.

In any lens system, the light rays going throught the exact center, do so, unchanged.
The pinhole eliminates the out of focus off center rays and only lets through the unchanged ones (which are in focus).
The reason these are not practical is that they eliminate peripheral vision and they require a bright source for the object you are looking at.

I've only fed my Himalayan Wellness and Innova. He definitely liked the Wellness better but he is a little on the er, uh, roly poly side and they don't make a lite formula. He doesn't like the Innova as much but is hair is less tangly and he isn't gaining weight. He's almost 12 and has had no (knock on wood) major health issues ever. I must admit though I am guilty of feeding him human treats because he only lives once and I figure he might as well get some enjoyment out of his life! To the lady that said "Meowmix" I suggest switching to a better food for like 2 days and you will notice the smell of his poo doesn't smell 1/100th as bad and his coat will be way softer. If you can feed your animal for under $10/month think about the great quality you are getting.... chicken beaks, claws, ground up road kill.... stuff that is really nasty, your cat is lucky he is still alive.
