I am into about three weeks of rigorous use of the cataract kit products and have indeed noticed an improvement in the glare issue. I’m not sure of the expected speed of results and in fact am also supporting treatment with vitamin regime and glutathione supplement as well as NAC drops. I will keep you posted as progress continues, and please feel free to email me with any suggestions or thoughts you may have as to length of use or combination of treatments for the homeopathy care from Biogetica.
