Newark, DelawareAges 16 years+ - NCT06477809Recruiting
Testing a device to help blind people with daily tasks
This trial tests a new device (ARIA) that helps people who are blind navigate daily tasks. If you have no light perception or only light perception, use a long cane, and are comfortable with a smartphone, you may be able to take part in 4 sessions in Sydney.
Sydney, New South WalesAges 18 years+ - NCT07073521Recruiting
Cognitive therapy for adjusting to vision loss

Common questions
- Are there clinical trials for blindness?
- Yes. Clin2 currently lists 222 recruiting blindness studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a blindness trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a blindness trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
