When you started noticing vision changes (whether before or after diagnosis) what did your changes look like? I just got updated prescription last month. No vision issues right now. I got diagnosed via genetic testing. My left eye all of a sudden just seems a tiny bit blurry. Almost like my contact has a smudge on it or something. They did change my right eye prescription to .25 better than what it was in the past. Now I’m wondering if my left scrip needs to be adjusted as well.

Hi,

I’ve been experimenting with a simple web tool to map perceived blind spots (scotomas) using dynamic noise.

The idea is that instead of using a static grid, the moving noise makes it easier to notice missing or distorted areas. You can click on those areas and generate a simple visual map.

It’s entirely browser-based, no data is collected, and you can export the result (JSON + image).

This is not a medical tool, just an experiment.

I’d really appreciate feedback, especially from people with macular conditions or anyone familiar with visual perception.

If anyone finds it useful and wants to support further development, there’s also a small support link — but feedback is much more important at this stage.

Thanks
