Is the promotion I saw for ReVision an accurate representation of benefits of this supplement for vision restoration? What percent of people with vision problems would be helped significantly by using this product?

We would say about 40% of people with vision problems would receive a significant benefit. This makes it quite worth trying simply by trial and error. As you know, many things are not well understood nor are they consistently diagnosed with accuracy. People also develop problems with aging and are prone to believe that the long-standing visual impairment they have lived with for many, many years necessitating glasses, for example, are simply worsening if there is a decline in visual acuity, when in fact there can be a more serious neurological degeneration underway and will not be perceived as a new issue, and a significant danger in the bargain that at some point might not be correctable by adjusting eyewear alone. This is where ReVision will shine, because it will work on that smaller minority of serious visual disturbances that have no known treatment as yet, but can wreak havoc and become irreversible and even lead to blindness. So we would say, like many such products, given the modest cost in terms of potential benefit and the low risk, being natural substances not in excess quantities, it is well worth trying for most people and kept in mind as an option should it not produce benefits for someone at the moment, to not rule out a retrial if things worsen with eyesight later on—to revisit and try another round of treatment could well save the day later, if not now, if a new problem develops that is more amenable to prevention with the active ingredients of this supplement.
