CR-39 Plastic: This is the most common material used for standard plastic lenses. It is a durable and lightweight material that offers good optical clarity.

Standard Refractive Index: 1.5 is considered the standard refractive index for regular plastic lenses. These lenses are thicker compared to high-index lenses (like 1.61 or 1.67), but they still provide good optical clarity and comfort for those with lower to moderate prescriptions. Clear Vision: These lenses provide high optical clarity and are suitable for most everyday vision needs. They deliver reliable and clear vision without distortion.

Lightweight: Although not as lightweight as high-index lenses, 1.5 plastic lenses are still lighter than glass lenses, making them a comfortable option for long wear.

Affordable: One of the main reasons these lenses are popular is their affordability compared to high-index or specialized lenses.
