This product is being heavily promoted, but there is little evidence that it will improve eyesight. It is basically a combination of vitamins - check out their website. While there have been a few medical reports that some ingredients in this combination may slow up the process of macular degeneration (MD), or perhaps reduce the likelihood of onset of MD (less evidence of that), this does not demonstrate it has any effect on other problems with visual acuity. Only a small proportion of people with reduced acuity have MD, and their treatment should be under the direction of an ophthalmologist, not a salesman. Moreover, it's fairly expensive, and one can get the same basic ingredients far cheaper than for the cost of Claroxan.
So, while I can't prove this is snake oil, the exuberant promotional claims and lack of proof certainly make it sound like that to me.
