Polycarbonate is one of the strongest and safest materials on the market. They have exceptional strength and resilience. They will survive the impact of a steel ball travelling at 160 km/hr without shattering which meets EN/EU grade for Low Energy Impact Resistance (small particle).
Our entry level glazing packages offered for our rimless and semi-rimless glasses are polycarbonate lenses. Due to the nature of these types of frames where the lenses have to be drilled or clipped into the frame, polycarbonate will greatly reduce the possibility of damage.
