Second Eyes
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Second Eyes turns a phone into a second pair of eyes for people with low or no vision. Point it ahead and it speaks what is in your path, in English, 中文, Bahasa Melayu or தமிழ். A cane finds the step and the kerb. It cannot reach the branch at head height, the glass door that looks like an open doorway, or the moment a footpath quietly becomes a road. Second Eyes watches for exactly those. Second Eyes blurs faces on the phone itself, with a visible status indicator when blurring is off. Frames go to Meta's models. SAM 3.1 fires the first warning for steps, kerbs and doors; in my testing, about 1.5 seconds. Muse Spark 1.3 follows with the context: what is ahead, which side, how many metres. Say "Hey Eyes" and ask anything, hands free. One rule above all: Second Eyes says what is in your path, and never says it is safe. It is designed to describe a road, never to decide when you cross. It is a research prototype and it can miss hazards; it gives information, not instructions. Built and tested on real walks in Singapore during the hackathon, by a solo builder. The public demo runs in your browser for 3 minutes, nothing to install.
