Frankly , I do not believe self hypnosis will help you with your eyesight
Short-Sightedness , most will say , that it cannot be elevated . Even with appropriate eye care tools such as glasses and lenses , the eye still degenerates . It constantly degenerates until it stabilizes when you mature , which depending upon the person , is 18-25 years old .
Though some belief that with proper eye relaxation techniques and exercises , the eye can be cured and be less short sighted eventually returning to 20/20 vision and there have been testimonials and results from this .
Though many argue upon its validicity . It may not help much but it is something you can look into
