It certainly is easier than plate-zapping which I had great success with.
I noticed that the rife frequencies I have on hand are specific for eye-inflammation, blurred vision, and eye-arteriosclerosis.
Intrestingly, I had success with the plate-zapping when I zapped with the eye speciman touching the artery speciman. Even though the plate-zapping brought success for me; I am amintaining with the f-scan2. MUCH easier!
I continue to enjoy near perfect vision - that 'lazy eye' is no longer noticeably 'lazy'. I am using my reading glasses less and less. Even if I don't have the perfect lighting for reading small print.
btw: I was always nearsighted in one eye and far sighted in the other [the lazy one].
