🔎 About 40% of adults have astigmatism but lots of them have no idea what that really means

🤩 I find that visual demos are the best way to make ideas like this clear!

🤓 In addition to the quick visuals in this video, I'll sometimes rotate a lens for astigmatism in front of parallel laser lines to show how different axes of the lens bend light differently

🌐 This video is from my Larry Laser YouTube channel where I share daily videos about how light and optics shape our world.
