airman duties.

(d) Normal fields of vision.
(e) No acute or chronic pathological

condition of either eye or adnexa that
interferes with the proper function of
an eye, that may reasonably be ex-
pected to progress to that degree, or
that may reasonably be expected to be
aggravated by flying.

(f) Bifoveal fixation and vergence-

phoria relationship sufficient to pre-
vent a break in fusion under conditions
that may reasonably be expected to
occur in performing airman duties.
Tests for the factors named in this
paragraph are not required except for
persons found to have more than 1
prism diopter of hyperphoria, 6 prism
diopters of esophoria, or 6 prism
diopters of exophoria. If any of these
values are exceeded, the Federal Air
Surgeon may require the person to be
examined by a qualified eye specialist
to determine if there is bifoveal fixa-
tion and an adequate vergence-phoria
relationship. However, if otherwise eli-
gible, the person is issued a medical
certificate pending the results of the
examination.
