Yep, there have been several studies done, ranging from media to education to optometric.
• CNET found that readers were 35% more likely to finish reading an article if they were reading with BeeLine turned on. See more on the CNET study in this article in The Atlantic [1].
• An optometric study using eye-tracking glasses found that BeeLine reduced the number of regressions and/or skipped lines for the vast majority of participants.
• Various educator-led studies (some more rigorous than others, and none as informal as the "case studies" that are unfortunately common in edtech) have found strong gains in reading fluency and/or comprehension.
I totally appreciate your skepticism, which is especially reasonable for someone who does not personally see a benefit from the tech.
The response from doctors who work in vision has been very positive, and our tools are recommended by doctors at Stanford Med School and UC Berkeley School of Optometry.
We even got featured by the American Optometric Association. The AOA committee that evaluated our technology said that this was the first time they'd ever had a unanimous vote in favor of anything. Apparently to them, it was quite obvious that this has beneficial effects (without having run any formal studies on it themselves).
To your point about colorblindness, I would note that I regularly come across people with red/green colorblindness who love/use our product. You can change the colors to be whatever you want, or use it in grayscale.
We are talking with publishers, but mostly on the digital side. Thanks for the input and questions!
