It is considered a way to help those who are visually impaired. Now, while sans-serif fonts might not help with dyslexia. One of the big issues for me with those fonts is the contrast with those fonts, but it might just be poor website design. Considering Dyslexia is mostly a neurological issue, generally, visually changes won’t help but perhaps it makes the page more fun and inviting which might encourage readers. I find those fonts (Dyslexia, etc) a bit hard to read myself and with over 7 studies it has yet to be proven effective.

Special fonts like Dyslexie and OpenDyslexic were created for that purpose, to be easy to read.

Those with disabilities such as Dyslexia would say the opposite about serifs, stay far away from serif typefaces and focus on sans-serif.
