Product is what I have used for over 10 years. It has retarded cataract operation for multiple years. It retards cataract growth. It has other needed vitamins as well.
I have been taking it for many years. My eyes are almost 83 years old, and every time I have them checked, the opthalmologist always comments on how good my eyesight is for ANY age. I read for at least half a day most days.
Tried doing 2 per day, but has to be 4 capsules a day to work. Has helped my closeup vision quite a bit. Did it restore it to 20/20, no, but it helps to not have to wear readers all the time to read.
