Natural Vision Therapy

In recent times with all the technological advancement in this Industry should our focus shift completely?

Many a conversations with Doctors, Opthamalogist and citizens have caused me to ponder over the above question. Being more specific, is laser, LASIK or LASEK as they are commonly termed as, the only option for correction of various Vision difficulties? I would appreciate if anyone could play the role of a Professional and enlighten me and millions of people with the same doubt. DOES NATURAL THERPAY TO CORRECT VISION REALLY EXIST? And if it does..Where?
