Hmm, we have actually never gotten that! Can dig into it.

What browser/device are you on? We don't support mobile (added this to post!) because the vision charts need to be displayed at a certain size. There's usually a warning that pops up for mobile, but it's earlier in the flow than what we posted to HKN.

I'm using Mac OS 10.15.7

I don't see any circles.

As a general comment, this whole test procedure seems very crude. If I saw overlapping circles with my glasses on, like in some of your tests, I would say that my prescription was way off. A better prescription is necessary long before you get to that point.

We're looking into this circle bug -- very sorry about that!

I won't argue that the current test isn't crude. We're rolling out increasingly sophisticated versions with each update, but I agree that in its current state our exam has a ton of room for improvement.

I do have to mention that the 1) vision check (e.g. do you see 20/20 with you current/expired prescription) and 2) the eye health tests are two different portions of our exam and serve two different purposes.

These latter set of "low-tech" maneuvers (double vision, amsler grid, red desaturation) are very high-level screening mechanisms for more serious underlying issues and do not have much to do with the numbers on a person's prescription. To be more specific, the overlapping circles are meant to assess if someone is having double vision, which in a worst case scenario could be a symptom of acute cranial nerve palsy.

I also had no circle, just a red square.

Thank you, really appreciate the detailed feedback! It seems like it is likely the no-script, will look into this soon.

The exam we provided is just a free sample for folks to play with - contact information is collected for paying customers (in a slightly different flow).

Did you do the exam on mobile or desktop? Also, what browser were you using?

[ars]

Desktop, using Firefox on Windows, with no-script active. That last part might be the issue - everything seemed to work until the end - it would not let me submit, then I disabled no-script, and I submitted, but it never asked me for contact info?

Not sure how you'll get back to me, it never asked for an email or anything.

The no-script might be at fault though. You might consider not using any CDN for scripts, only host locally.

I did not try again because I don't have a prescription (I submitted an image saying "no prescription"), and I realized it can't do anything for me (I just wanted a checkup basically - just tell me how I did on the various sized letter thing).
