The Ultimate Guide to Oakley Prizm Lenses
21/04/2026
When choosing new glasses, most people focus on the frame style or lens prescription. But lens coatings can dramatically improve comfort, durability, and visual clarity. During dispensing, you may hear terms like anti-reflective coating, anti-glare coating, or anti-scratch coating – but what do they actually do, and are they worth it?
This guide breaks down the most common eyeglass lens coatings, explaining how they work and who benefits most from each one.
Anti-Reflective (AR) coating – sometimes called anti-glare coating – is a thin, multi-layer coating applied to both sides of a lens to reduce reflections from light sources.
Normally, light hitting a lens reflects off the surface. Those reflections can create distracting glare, halos around lights, and reduced clarity – especially at night.
An anti-reflective coating works by allowing more light to pass through the lens instead of bouncing off it. This improves visual clarity and reduces glare.
Benefits include:
Without AR coating, lenses can reflect up to 8-10% of light, creating noticeable glare.
Anti-reflective coating is particularly valuable for:
High-index lenses (used for stronger prescriptions) reflect more light, so AR coating is almost essential for them.
Yes, anti-glare coating and anti-reflective coating refer to the same technology.
The term “anti-glare” describes the benefit, while “anti-reflective” describes how it works. Both mean the coating reduces reflections on the lens surface.
Some premium coatings may also include additional layers that resist smudges, dust, and water, making the lenses easier to clean.
Modern lenses are typically made from plastic materials such as polycarbonate or high-index plastics, which are lighter and safer than glass. However, plastic lenses can scratch more easily.
An anti-scratch coating (also called a hard coating) adds a hardened protective layer to the lens surface to improve scratch resistance.
It’s important to understand that no lens coating makes glasses completely scratch proof. However, anti-scratch coatings significantly reduce damage from normal handling.
Anti-scratch coatings are especially useful for:
Most modern prescription lenses now include a hard coating by default because of its value.
When purchasing glasses, you may encounter several additional coatings that improve comfort and performance.
Designed to reduce exposure to high-energy blue light emitted by digital screens.
Benefits may include:
Best for people who spend 6+ hours per day on screens.
Many lenses include UV-blocking layers that protect eyes from harmful ultraviolet radiation.
Benefits:
Polycarbonate lenses already provide 100% UV protection.
Premium AR coatings often include layers that repel:
These coatings make lenses much easier to clean and maintain.
Our premium brand, ZEISS, is a global leader in optical technology and is well known for its continuous innovation in lens coatings, particularly with its DuraVision range. These coatings are designed to enhance visual clarity, reduce reflections, improve durability, and make lenses easier to clean, ultimately everyday comfort and lens longevity.
Designed specifically for sunglasses, this coating adds anti-reflective properties to the back surface of tinted lenses. It reduces glare from behind, improves contrast and clarity outdoors, and maintains the cosmetic look of sun lenses.
A more affordable, entry-level coating that still offers ZEISS anti-reflective benefits. It provides good clarity, durability, and ease of cleaning, with a subtle green reflection – ideal for everyday wear at a lower price point.
A premium coating focused on durability and clarity. It offers superior scratch resistance (up to 3x harder than previous coatings), reduced reflections (over 50% less glare), excellent cleanability, and a subtle blue residual reflection. It’s a great all-rounder for patients wanting long-lasting performance.
The newest and most advanced ZEISS coating. It provides the highest level of scratch resistance, significantly easier cleaning, improved low-light clarity (great for night driving), and reduced reflections, all with a distinctive gold hue for a premium aesthetic.
Overall, the DuraVision range progresses from good everyday performance (Chrome), to high durability and clarity (Platinum), through to the ultimate premium option (Gold), allowing patients to choose based on lifestyle, visual demands, and desired aesthetics.
For most people, yes – especially anti-reflective coating.
While basic lenses will correct your vision, coatings improve the comfort, durability, and overall experience of wearing glasses.
The lens coatings that typically deliver the most value are:
These features are often bundled into premium lens packages that provide better long-term value.
Lens coatings may seem like optional extras, but they can significantly improve the performance and lifespan of your glasses.
When dispensing new glasses, understanding these lens coatings helps ensure you choose lenses that match your lifestyle, work habits, and visual needs.
If you’re unsure which coatings are right for you, our optometrists and optical dispensers can recommend options based on how and where you use your glasses everyday.
