the first real eye book written by bates is the best sun gazing info i have read that i trust and gave be confidence to try it...
beware all those alive today, using u-tubes and dvd promoting them selves as the best, many times it is only to make more $$$$$$$$$$$$$...so take what they say and self experiment if it makes sense to you..
sun gazing is not an easy subject for most adults...if you don't handle it correctly you will never benefit and can easily hurt your eyes.....you must have "faith" that we are compressed sunshine an sun provides life for all....respect the sun and it will support your life..
