How important is the Spectacle Frame Bridge Deformation Tester and how to use it？

A pair of glasses is like a pair of regenerated eyes for those of us with poor eyesight, 
which brings great convenience to our lives, so the stability of the use of the glasses
bridge becomes particularly important. The function of the glasses bridge deformation 
tester is The measurement frame has a certain ability to retain the lens, which ensures 
that the frame can be safely worn for more than 2 years, and prevents the lens from 
falling off due to slight impact, which affects the wearing effect. It is used by mounting 
the glasses horizontally on the test unit with the outer lens facing down. One lens is 
clamped in place while a vertical force is applied to the other lens. After the force 
is removed, measure the relative horizontal permanent deformation of the side under 
test and perform a compliance assessment.
