I've had my BEMER for 10 years now and love it, I had several issues that prompted me to purchase one. Now I sell them. I've shared it with my diabetic sister, who was experiencing small bleeds in her eye, they would occur monthly, and would leave her blind for a couple of days until the blood could drain/clear. The BEMER really helped and she no longer has these bleeds. It's not so wacky really - NASA has looked into the technology and will be incorporating it into the linings of spacesuits, to help with muscle atrophy, bone loss and hydration issues from being in a zero gravity field. There are studies on PubMed and plenty of science and research behind it. I've seen amazing slides from Doctors that show improvement in the eyes from a variety of conditions. There is a video from Dr Todd Wylie in Spokane WA if you like I can share the link. You could purchase one and use it for 30 days - return it if you're not happy with your experience using it, there is a 10% restocking fee. The results are cumulative so the longer you use it - the better! It's a system regulator so you're resetting your body's natural rhythms to a balanced state.
