From the relative thickness, for the same lead equivalent, acrylic/plastic has approximately five times, and lead-quality glass significantly reduces the ability to observe, for example, lead at 1.8 mm to 2 mm, lead glass is 5/16 thick. Acrylic/plastic will be about 1/2 thicker in protection, acrylic/plastic extra thickness may require special frames, and LX lead glass is suitable for standard size frames.

TheIn terms of resistance to discoloration, acrylic/plastic fades when exposed to ultraviolet light. Acrylic/plastics are also prone to discoloration, chemicals used in everyday use, such as cleaning materials...even smoke. The radiation caused by lead glass of lx-57b is not discolored and has high chemical resistance. The durable LX glass maintains its attractive visual clarity.

TheIn terms of light transmittance, glass can be lighter than acrylic/plastic for the same lead equivalent.

TheIn terms of flammability, the x-57b lead glass is a non-flammable material due to its glass. Acrylic/plastic is flammable. When acrylic/plastic burns, toxic gases are emitted. This does not happen with LX lead glass.

TheIn terms of surface hardness, the lx-57b lead glass is mirror polished. The lead glass of lx-57b is tested with a Moh's hardness scale of grade 6 (compatible with feldspar granite). Acrylic/plastic grade 3 exam (equivalent to calcite, limestone, and chalk).

TheIn terms of wear resistance, lead glass of lx-57b has greater scratch resistance due to its hard surface. Unlike glass, acrylic/plastic can be easily scratched and cleaned due to its soft surface, reducing its light transmittance and clarity.
