vision improvement
I'm a student pilot with over 20 hours. and i want to become one day a proffesional pilot. The problem is that my glass number is about -5 with some astigmatism. so i'll have a problem getting class 1. I heard about natural vision improvement, and even bought a book on the subject and started training about a month ago. yet without results. did someone try natural vision improvement techniques? should I buy a vision improvement product such as america20-20, vision freedom, etc.?had someone here tried those?
i'll really appreciate any help.
