Is APEL eyewear the only authorized sunglasses in Army uniform even while in garrison?

Is it true that there is a new regulation stating APEL eyewear is the only authorized sunglasses while in uniform even in garrison, and this regulation supersedes AR 670-1? If so, what is the regulation?

AR 670-1 dated 10 APR 2015 paragraph 3-10 seems to address the difference between sunglasses and protective eyewear, as it states the following:

(3) Eyeglasses or sunglasses that are trendy or have lenses or frames with conspicuous initials, designs, or other adornments are not authorized for wear. Soldiers may not wear lenses with extreme or trendy colors, which include, but are not limited to, red, yellow, blue, purple, bright green, or orange. Lens colors must be traditional gray, brown, or dark green shades. Personnel will not wear lenses or frames that are so large or so small that they detract from the appearance of the uniform. Personnel will not attach chains or ribbons to eyeglasses. Eyeglass restraints (to include bands) are authorized when required for safety purposes. Personnel will not hang eyeglasses or eyeglass cases on the uniform and may not let glasses hang from eyeglass restraints down the front of the uniform. Glasses may not be worn on top of the head at any time.
(4) Soldiers are authorized to wear ballistic spectacle eye protection issued by the Army, including lens colors or logos that do not comply with paragraph 3–10 a (3), above, in garrison or field environments unless otherwise directed by their chain of command. See the Army Combat Readiness Center for a list of currently approved protective eyewear.
