Lens retention in metal and zyl safety frames was tested using both a high mass (500 g), low velocity impact (HM-LV), and a low mass (1.04 g), high velocity impact (LM-HV) for plano polycarbonate lenses of various thicknesses.
The results showed that the metal safety frames retained lenses better than the zyl (p<0.01) after a HM-LV impact.
For the LM-HV impact, metal and zyl frames performed equally (p=1.00).
Lens thickness was not a factor in lens in frame retention for the HM-LV impact (p=0.958).
However, for the LM-HV impact, 1.6-mm thick lenses were more easily displaced than lenses with thicknesses of 2.0,2.4, and 3.2 mm (p=0.003).
