EDITED TO ADD
From CFP 265
Chapter 2 Section 2 Apperance
EYEGLASSES/SUN-GLASSES
11. Eyeglasses and sun-glasses shall be
conservative in design and colour.
12. Subject to any restrictions which may be
imposed by commanding officers on occasions of
wear, the following sun-glasses are authorized for
wear with CF orders of dress:
a. Designated Duty Personnel. Personnel
serving in aircrew, field and other designated
positions may obtain from the CF Supply
System and wear:
(1) Sun-glasses (aircrew) 8465-21-870-
6020,
(2) Sun-glasses (field force) 8465-21-104-
7821, and
(3) Sun-glasses (special) 8465-21-874-
0579.
b. All Personnel. Personnel who normally wear
eyeglasses, may wear either conventionally
framed prescription sun-glasses or
conservatively styled clip-on sun-glasses,
when conditions and circumstances dictate.
Others may wear conservatively styled sunglasses
which conform in general
appearance to those previously noted.
13. The following types of lenses are not
authorized for wear with CF orders of dress:
a. Photochromic. These lenses act as a light
filter and possess the property of darkening
when exposed directly to ultraviolet light and
lightening when the ultraviolet is withdrawn.
b. Mirrored. These lenses, also referred to as
half-silver mirrors, have a highly reflective
metallic substance deposited upon the
surface of the lenses, thereby creating a
mirrored effect.
Note the part I bolded..... have seen lots of ppl with those... not sure if there has been an update to CFP 265 yet on this...
