Good Morning!
Yes I beleive the lemon eye wash does work. Here is the link where I read of it. http://www.universal-tao.com/article/perfect.html
I am going to try and do it a couple times a day. The eye cup is used with washing your eye. It is class and small.
Here is the url of Dr. Christopher's site http://www.drchristophers.com/
There youcan look at their products and etc.. I love his products. With the eyebright you can get the pills or extract. I have the extract. It says to take it as an eyewash or internally. I am going to do them both at the same time.
If you stay consistant with the exercises I am certain you would see big improvement. Yeah the 3 cups exercise is my favorite too. I often do it during the day with anything that comes handy. Two tree trunks,when eating at the table, my fingers, picture....
I have an eye appointment soon. I really wonder what my eyesight will be..=)
