Answer: (B)

The quality of today’s polycarbonate lenses has seen significant improvements primarily due to the demand for compact discs. As the use of compact discs became widespread, there was a notable need for durable materials that could withstand scratches and impact while maintaining optical clarity. Polycarbonate, known for its strength, lightweight nature, and excellent optical properties, emerged as an ideal solution for manufacturing compact discs. This increased demand led to advancements in polycarbonate lens production, enhancing their quality over time.

While other products like smartphones, contact lenses, and sports eyewear have contributed to various innovations in optical materials, compact discs specifically drove the enhancement of polycarbonate technology, paving the way for its applications in eyewear and various optical devices.
