How to Choose the Right Prescription Lenses

Choosing the right prescription lenses depends on how you see, how you live, and what you expect from your eyewear. The lens type you select affects clarity, comfort, thickness, and long-term durability.

  • Single vision lenses correct one field of vision—distance, near, or intermediate—and are ideal for everyday clarity.
  • Progressive lenses provide seamless vision at all distances without visible lines, making them a popular choice for multifocal wearers.
  • High-index lenses are designed for stronger prescriptions, offering a thinner, lighter lens profile for improved comfort and appearance.
  • Specialty lenses may include blue-light filtering, occupational designs, or digitally optimized lenses for extended screen use.

Lens coatings like Crizal® Rock can be applied to most prescription lens types to improve durability, clarity, and ease of care—regardless of your prescription strength.

What Is Crizal® Rock?

Crizal® Rock is Essilor’s most durable anti-reflective lens coating, engineered for people who expect their glasses to withstand daily wear without sacrificing optical clarity. Designed using a high-density molecular structure, Crizal Rock resists scratches, smudges, dust, and reflections more effectively than standard AR coatings.

This advanced coating is built for real-world conditions—keys in pockets, frequent cleaning, long days at work, and constant handling—making it an ideal choice for anyone who wants premium performance with minimal maintenance.

Key Benefits of Crizal® Rock Lenses

  • Exceptional scratch resistance: One of Essilor’s most abrasion-resistant coatings for long-lasting performance.
  • Superior anti-reflective clarity: Reduces glare from screens, headlights, and overhead lighting.
  • Smudge and dust resistance: Hydrophobic and oleophobic layers help lenses stay cleaner longer.
  • Easy to clean: Less buildup means fewer wipes and clearer vision throughout the day.
  • Long-term durability: Designed to maintain performance over years of everyday use.

Prescription Compatibility

Crizal® Rock can be applied to most prescription lenses, including single vision, progressive, and high-index lenses. It is especially well-suited for higher prescriptions, where lens durability and clarity are critical.

The coating is compatible with a wide range of frame styles and lens materials, making it a versatile option whether you’re updating everyday glasses or investing in premium eyewear.
