Why check the tension in mounted lenses
Every lens that is mounted in a frame is under some tension. If it is wrongly applied, the tension can distort the lens and, in glass lenses, cause chips. A tensiometer shows the tension so that you can remove it before the glasses go to the customer, which means fewer complaints and remakes.
