Natural Treatment For Improving Eye Sight?

Hi guyz,
Just wanna know about the Natural treatments available for Correcting or Improving vision.I have a slight Astigmatism of less than 1 in both eyes. I am planning to have a career in Armed forces(may be flying). So i want to know about any Natural or Alternative treatment available for Rectifying this condition. I dont want to go for Surgical procedure like LASIK or PRK.Lasik and PRK are not a strict taboo in forces and they can be easiy detectable thru a test. I have heard about Bates method and Exercises, but dont know how much effective they are in correcting Astigmatism. Please advice.
Thanks in advance.
