SightFrame: A live vision simulator for education and accessibility

Hi Product Hunt — I’m the developer of SightFrame. I built SightFrame after seeing how difficult it can be to explain visual differences with words alone. It lets people explore adjustable, visual approximations of conditions such as myopia, astigmatism, color-vision differences, and night glare in a short, focused workflow. It is designed for education, accessibility conversations, and design reviews — not diagnosis or treatment. I’d love practical feedback from educators, accessibility practitioners, designers, and anyone who has had to explain how a scene may look different: 1. Which scenario would be most useful in a real conversation? 2. Which effect is unclear or potentially misleading? 3. What would make the demo easier to understand? Please tell me what you would improve. I’m here to learn, not to ask for upvotes.
