Revenue at the group, which produces a wide range of spectacle frames and lenses, including sunglasses and safety glasses, for markets across the world, increased by 6% to £111.1m in the six months to 30 June.
In a half-year trading update to shareholders, the group said strong cash generation during the period meant net debt decreased by £5m to £22.6m.
It also invested £900,000 on its new manufacturing facility in Vietnam.
Inspecs, which floated on the London Stock Exchange’s AIM market three years ago, was forced to reshuffle its board last October following the resignation of its chair, former Tesco boss and City grandee Lord MacLaurin.
A warning over future sales made at the same time resulted in its shares losing half their value.
However, a rebound in its European markets and continued growth in others gave it a more positive end to 2002 which continued into this year.
