What is Myopia, Hyperopia, and Astigmatism? 

I hate my astigmatism :(

I have astigmatism and I am getting quicksilver glasses on Saturday. Thx for the full description

Great job explaining the issues. Thanks a lot! I visited an optometrist yesterday to discuss a lasik procedure. She told me I have both Myopia, and Astigmatism, and she gave me two options do tack about and decide. This video has helped me understand the issue, and will help me in future discussion with my optometrist, and making decisions in this regard. Best regards and gratitude
