A Keyboard with a Blue Keypad - Advocacy. High Quality Render of a Conceptual Keyboard Keypad. The Keypad is Blue in Color and there is Message Advocacy on It. AFB advocates for policies that promote accessibility, equity, and opportunity for people who are blind or have low vision. We write advocacy letters and statements to influence and inform the public and policymakers about key issues, and we comment on federal rulemaking and requests for information. Often, we find it useful to work in coalition, which strengthens our collective voice, through joint letters and comments.
