Hello M.,

This morning I read the article concerning unexplainable vision loss.
I am specialized in strabology in an autodidactical way.
I've met with this matter before and came to the conclusion that, besides the reasons you gave in this article, this also occurs in non-Alzheimers patients.
The clients I've seen varied in age from 6 up to 81 years. The elderly clients were not suffering of Alzheimers !!
Special spectacle lenses may prevent or solve this problem.
