Welcome. Would you be interested in sharing your experience using bitcoin wallets? We did accessibility research last year in the bitcoin design community and found a lot of problems with wallets that basically made them unusable. Common problems were QR codes that were not annotated for screen readers, modals that could not be closed, icon buttons without labels, etc. There is more information on the accessibility page here in the design guide. Most are fairly simple things to fix from a technical perspective, and we sent our test results to various projects and filed issues. However, we do not have anyone in the group who is low-vision, so learning from your lived experience could help in really understanding what needs to be improved.
