His Eyes

The question we get most often... so what can Joseph see?

It's hard to believe that there these beautiful baby blues

Don't see much.

These are part of his field of vision test:

(Left and Right Respectively)

The black parts are where he cannot see, it's not black or white,

he says it's just blurred beyond comprehension.

Besides the blurred spots, his eyes are constantly shaking.

This is called Nystagmus (click for more info)

Definition of Blindness from the National Federation for the Blind (NFB)

The federal statute defines blindness as follows:

[T]he term "blindness" means central visual acuity of 20/200 or less in the better eye with the use of a correcting lens. An eye which is accompanied by a limitation in the fields of vision such that the widest diameter of the visual field subtends an angle no greater than 20 degrees shall be considered for purposes in this paragraph as having a central visual acuity of 20/200 or less.

In a letter from his Ophthalmologist Dr Deitz :

"[Joseph] has bilateral optic atrophy,

resulting in the best corrected vision of 20/400 in either eye."

Most of the time when asked, I say he is blind,

only when pressed further I will elaborate

on what he can and cannot see.

I hope this answers the question.
