Lens coatings you’ll need to care for your lenses

Reviewed by Dr. Justin Asgarpour

Lens coatings help protect and enhance your lenses. They allow more light to pass through your lenses to your eyes, so you can enjoy sharper and clearer vision. From reducing the glare of digital devices to protecting your lenses from daily wear and tear, lens coatings can extend the life of your lenses and provide comfort throughout the day. Made of a hard, thin film that is layered on the lens, a lens coating can last up to two years or more.

Whether you wear single vision glasses, progressive glasses, photochromic glasses or polarized sunglasses, having a high-quality lens coating on your lenses will make a difference on a daily basis and in the long run.

Anti-fog Lenses are a perfect addition if you regularly wear a face covering with your glasses. The Anti-fog coating fights condensation quickly, so when there’s a temperature change that causes your lenses to fog up, they’ll clear almost instantly. Anyone who has worn a face mask while also wearing glasses knows how frustrating it can be when your lenses fog up. Anti-fog Lenses solve this problem – they’re quick to clear and remain clear, for fog-free vision inside and outside.

Anti-reflective glasses are a great choice for those who want to see and be seen more clearly. They are designed to minimize distracting reflections from both sides of the lens to improve vision for driving at night. Anti-reflective lens coating helps your vision appear crisper, your eyes look clearer to others, and your lenses look more attractive without the reflections. Anti-reflective coating is also included in the C Shield coating. The AR coating is included on all lenses except the Standard Lens.

UV protection for glasses blocks 100% of UV light, so you can better protect your eyes from potential damage, such as cataracts or macular degeneration.

This protection can be achieved either through the use of a UV protective coating, or through the properties of the lens material itself.

While our Clear Standard Lenses do not have UV protection, higher index lens materials like Thin Air and above feature built-in UV protection by virtue of the material itself. You can make the most out of that protection for your eyes by ordering higher index lenses, Transitions® glasses or polarized sunglasses.

The scratch-resistant coating creates a harder lens surface for your glasses, making your lens surface 10 times harder than uncoated lenses. It makes the surface more resistant to scratches and protects against everyday wear and tear on your lenses.

All of our lenses come with scratch-resistant coating to help extend the life of your lenses for clearer vision. An even stronger and longer lasting scratch-resistant coating is included in the C Shield coating.

C Shield is the lens coating that changes everything. It’s water, smudge, and scratch resistant. It’s anti-static and anti-reflection. It’s designed to handle whatever your day has in store. Clever and capable, C Shield takes care of your lenses so you can take care of your life.

The scratch-resistance is present on both sides of the lens, which makes your lenses last longer. The anti-static and smudge repellent properties mean you'll have to clean your glasses less often which is more convenient and will extend the durability of your lenses.

Top 3 FAQs about lens coatings

Having an anti-reflective coating minimizes distracting reflections on the inside of the lens itself. It ensures more light reaches your eyes rather than bouncing off or inside your lenses. This allows your eyes to take in more light, so you can enjoy better vision in your day-to-day activities.

An anti-reflective coating also makes your eyes look more natural when people are looking at you. A lens without coating can create a distracting "mirror" effect that takes attention off of your eyes.

While most lens manufacturers offer anti-reflective coatings, the performance and durability vary. The best coatings have oleophobic (grease-resistant) and hydrophobic (water-resistant) properties, making them easier to clean and less likely to become smudged.

Top performers in coatings also change their composition slightly for each type of lens material that they're applied to — this is called "index matching". It increases a stronger bond and better durability under harsh temperature conditions. Our premium C Shield coating is both oleophobic and hydrophobic as well as index-matched to the specific lens material you choose.

Adding an anti-glare coating after you've already purchased your glasses is not recommended for the following reasons:

  • a. It could cost more and affect quality: Since the coating application technology requires a coating to be added at the time that the lens is cut, it could cost more to apply it after purchase and you may not get the same quality.

  • b. Your lenses are not factory “fresh” anymore: Once your lenses have been exposed to skin oils, the coating may not stick well, which could defeat its effectiveness and longevity.

  • c. Scratches on lenses could be magnified: If there’s a scratch, applying the coating will magnify it.
