Lens Coating Options Explained

Modern eyeglass lenses offer much more than just vision correction. With a variety of specialized coatings available, your lenses can be customized to enhance durability, comfort, and performance. This guide will help you understand the various lens coating options available and how they can benefit your visual experience.

Essential Lens Coatings

Anti-Reflective (AR) Coating

Anti-reflective coating reduces glare and reflections on your lenses, allowing more light to pass through to your eyes. Benefits include:

• Clearer vision, especially in low-light conditions and night driving
• Reduced eye strain during computer use and reading
• Better appearance—others can see your eyes instead of reflections
• Enhanced visual clarity in photographs and video calls

Premium AR coatings like Crizal® also incorporate smudge-resistant, water-repellent, and anti-static properties that keep lenses cleaner longer.

Scratch-Resistant Coating

While no lens is completely scratch-proof, scratch-resistant coatings create a harder surface that's more durable against everyday wear and tear. This coating is particularly beneficial for:

• Children's eyewear
• Active lifestyles
• Polycarbonate and high-index lenses (which are naturally softer)

Most quality lenses include some level of scratch protection, but premium options offer superior durability.

UV Protection Coating

UV protection is crucial for long-term eye health. This coating blocks harmful ultraviolet rays that can contribute to cataracts, macular degeneration, and other eye conditions. While polycarbonate and high-index lenses inherently block UV light, other materials may require additional protection. We recommend 100% UV protection for all eyewear.

Specialized Performance Coatings

Blue Light Filtering

Blue light filtering coatings help reduce exposure to high-energy visible (HEV) blue light emitted by digital screens, LED lighting, and the sun. These specialized coatings may help:

• Reduce digital eye strain symptoms
• Improve visual comfort during extended screen time
• Potentially help maintain healthy sleep patterns by reducing blue light exposure in evening hours

Options range from nearly clear lenses with subtle filtering to those with a noticeable amber tint for maximum blue light reduction.

Photochromic/Transitional Lenses

These innovative lenses automatically darken when exposed to UV light and return to clear when indoors. Modern versions like Transitions® Gen 8 offer:

• Faster activation and fade-back times
• Better darkening while driving (compared to older generations)
• Multiple color options beyond traditional gray and brown
• Protection from both UV rays and blue light
• Convenience of having sunglasses and clear glasses in one

Hydrophobic (Water-Repellent) Coating

This coating causes water droplets to bead up and roll off lenses rather than spreading and creating smears. Benefits include:

• Improved vision during rainy weather
• Easier cleaning with less smearing
• Reduced fogging when transitioning between temperature extremes

Oleophobic (Oil-Repellent) Coating

This coating resists fingerprints, skin oils, and cosmetics, keeping lenses cleaner and easier to maintain. It's typically combined with hydrophobic properties in premium lens packages.

Specialty Application Coatings

Mirror Coating

Mirror coatings reflect light away from the front of the lens, reducing glare while adding a stylish touch. These coatings come in various colors and intensities, from subtle to striking, and are popular for:

• Sunglasses and sports eyewear
• Snow and water activities where glare is intense
• Fashion-forward eyewear statements

Anti-Fog Coating

Anti-fog coatings prevent condensation from forming on lenses when moving between different temperature environments. This is especially valuable for:

• Winter sports enthusiasts
• Kitchen workers and chefs
• Healthcare professionals wearing masks
• Anyone who frequently experiences fogging issues

Caring for Coated Lenses

To maximize the lifespan and effectiveness of your lens coatings:

• Clean with a microfiber cloth and appropriate lens cleaner
• Avoid paper products, tissues, or clothing which can scratch coatings
• Never use household glass cleaners, which contain chemicals that damage coatings
• Rinse lenses with water before wiping to remove abrasive particles
• Store glasses in a protective case when not in use
