It does seem to be quite a legible typeface. I'm not sure about readable, given that it is sans-serif, but then, if the intent is to help people with poor eyesight, legibility rather than readability is what you would need to improve.
Well, it isn't especially ugly like most of the fonts that claim to cure dyslexia, but the "study" is more ridiculous than usual. And if we want to say there's a difference between legibility and readability, whatever it is, reading aloud is probably a whole third thing entirely, especially for a third-grader who only recently learned to write in sticks and circles.
Given that "Fonts are harming 7 out of 10 people. This one font can change that injustice" is a direct quote from an article about Lexend... yes, there is absolutely no excuse for a claim of that nature.
7 out of 10 people have bad eyesight, and there is a great conspiracy to make all existing typefaces require near-perfect eyesight to read well? Try telling me another one.
As a voracious reader, I must attest reading speed depends on how much books you've read, in whatever script you are most familiar with. No fancy font is gonna change that. This is my personal opinion.

Nice try.
They are easier to write, but harder to differentiate in reading for people who have difficulty differentiating letters. Especially the “a.”
