✅ Affordable: Budget-friendly option for those looking for quality lenses without high costs.
✅ Scratch-Resistant, With Coatings: Can be treated with scratch-resistant coatings for added durability.
✅ Blocks Some UV Rays: Provides partial UV protection, but additional coatings are recommended for full UV defense.

🔹 Individuals looking for a cost-effective lens option.
🔹 Those who primarily wear glasses indoors (as CR-39 lenses are less impact-resistant than polycarbonate).
🔹 People who prioritize optical clarity over durability.

Limitations of CR-39 Lenses

❌ Less impact-resistant compared to polycarbonate or trivex lenses.
