When it comes to healing your eyes, in this case, glaucoma causes damage to the optic nerves and this has caused the blindness. Now, one could argue that once the nerves are damaged, it is permanent. But scientists have come across a protein that has demonstrated the ability to rebuild the eyes and reverse blindness...There is some hope for that in the future of science.
I do believe you can heal your eyes but understand that this will demand a lot of energy and take time. The energy will need to build up and eventually build your nerves up cell by cell and then something will be regained. The only challenge here is patience and persistence. A lot of it.
Have hope and as long as you have the will.
Are you aware of the method(s) you will use to go about doing this?
