Hi, In my AGA FFM I have two small rubber "ears" located on both sides at
about the level of the eyes, just inside the face seal. I modified an old
pair of (reasonably small) metal framed glasses simply by cutting the bows ca
20mm long and bent the last 8mm upwards. I press the upward bent part of the
bows through the small holes in the rubber and they fit perfectly. All I
needed for the work was 20 minutes, a pair of pliers, and a file... Since
nothing crosses the face seal the fit is very good without any leakage into
the hood.

I believe you will have to check the measures of your bows to make shure you
get the right distance from your eyes to the glasses.

I think it might be an idea to contact your local Interspiro dealer, they
might sell a special frame specially made to fit in the FFM. I will try to
remember to ask Imre Botos at Interspiro the next time I see him and return
to you.

Regards and a very happy new year!

Ake Larsson
