I'm not a robot?

I have no problem with a captcha if it’s easy to read as a human, hard to read for a robot.  This captcha however is insanely hard to read.  I have great vision and since I’m using this on a small screen, I’m squinting to see the captcha text, and the contrast is so low I had to try 5 times before getting it right.  Can you please implement a less vague test?  I’m doing a bunch of testing with different lens distortion settings, and after a few model exports, I’ve now had to deal with this a lot.
