Is "good eyesight" on TV true? Who can tell me the details and effects? Also, what's its price?

Not so good. It doesn't work. Most products on the market now are used for health care. My child has used 1 for many years, and it is useless. If you want to treat them, try the eye yoga vision intensifier. It's good that my friend used it, but I haven't bought it yet. You can buy it in Beijing. I don't know the telephone number. I will ask you later.
