These days almost everyone has a camera in their phone. Luckily, our phone’s cameras don’t have an astigmatism, so they can be a great way to test whether or not the starburst effect we are seeing through our red dot is indeed our eye with an astigmatism, or an issue with the red dot itself. This video goes into detail on how to do that test with your phone - there are one or two tricks to getting the test just right. Have any further questions.
