I had a similar problem with my "visual fields" and had to do a MFT prior to reinstatement of my Class 2 AND to be considered for a Class 1 with OML.
Although not a CPL.. I took a MFT with the CFI on an SEP.. as I was doing my PPL but prior to going Solo.
Made to do 3 approaches with an emphasis on trying to spot other "traffic" and for the examiner to comment on my depth perception, ability to look out for traffic and GH.
