CR39 Lenses Features are:

Fragmentation: When plastic lens breaks, it breaks into larger fragments than their glass counterparts. Furthermore, the fragmented pieces are not as sharp as glass.
Fogging: CR39 lenses are less likely to fog-up than glass lenses because it responds more favorably to temperature changes.
Weight: Glass lenses are approximately 2X heavier than plastic lenses of similar size and shape. The lighter weight provides the wearer greater comfort.
Reflections: CR39 lenses have much lower internal reflection and surface glare than glass materials.
Tinting: CR39 lenses are great for tinting. Lenses can be tinted to virtually any color. Even lenses with variable thickness are able to be tinted evenly.

Today it is readily available to the public. It impact resistance makes the material extremely suitable for sports, industrial safety goggles, and children's eyewear.
Scratching: The reason for polycarbonate lenses' impact resistance is because of its "softness". Softer materials will flex instead of fragment when met with great force. However, the property allows lenses to be scratched easily. Therefore, every single one of our polycarbonate lenses is multi-coated with hard coating that forms a protective layer around the lenses allowing the lenses to be free from scratches while retaining its impact resistant qualities.
