Feature-by-feature
Our pitch
EYE CARE chose breadth: 12 languages, RTL, PWA, articles, glossary, persona pages, embed widget. 202020.io chose depth on the break protocol itself. Different bets.
Verdict
Either works for the core 20-20-20 use case. EYE CARE goes wider on languages, installability, and content; 202020.io goes deeper on the break protocol mechanics and product reviews.
