I think we communicated. Here is a reference from FAA 17-2021 FAA brochure on pilot vision.

A Word about Contact Lenses
Monovision contact lenses (one contact lens for distant vision and the other lens for near vision) make the pilot alternate his/her vision; that is, a person uses one eye at a time, suppressing the other, and consequently impairs binocular vision and depth perception. These lenses are not acceptable for piloting an aircraft.
