Perhaps the warm moist air you breath out is condensing on the inside surface
of the goggles. You might do better with a combined mask that doesn't allow
your outgoing breath to touch the inside of the goggles or separate goggles
and breathing filter. The goggles might have a filtered opening to allow
water vapor from your skin to escape, or they might be part of the incoming
airpath. Outgoing air might bypass the filter to avoid condensation there.
