Why Lens Coatings Matter as Much as the Frame
When investing in premium eyewear, most attention goes to the frame — its material, shape, and finish. But the lens coating is equally important to your visual experience, eye health, and the longevity of your glasses. Understanding the different types of lens coatings helps you make a more informed choice and get the most from your eyewear.

Anti-Reflective (AR) Coating
What It Does
Anti-reflective coating — also known as anti-glare or AR coating — reduces the amount of light that reflects off the surface of your lenses. Without it, up to 8% of available light is lost to reflection, reducing visual clarity and causing distracting glare in bright or artificial light environments.
Who Benefits Most
AR coating is particularly valuable for those who spend significant time driving at night, working under artificial lighting, or using screens for extended periods. It also improves the cosmetic appearance of your glasses — reducing the mirror-like reflections that can obscure your eyes in photographs and face-to-face conversations.
Premium vs Standard AR
Higher-quality AR coatings are also hydrophobic (water-repellent) and oleophobic (oil-repellent), making lenses easier to clean and more resistant to smudging. This is a meaningful quality difference that becomes apparent in daily use.
UV400 Protection
What It Does
UV400 protection blocks all ultraviolet light with wavelengths up to 400 nanometres — covering both UVA and UVB rays completely. This is the gold standard for UV protection in eyewear and is essential for long-term eye health.
Why It Matters
Prolonged UV exposure is a leading cause of cataracts, macular degeneration, and other serious eye conditions. UV400 protection is non-negotiable in any quality sunglass lens, and increasingly important in everyday prescription lenses as well. All premium sunglasses in our sunglasses collection meet UV400 standards.
A Common Misconception
Darker lens tints do not automatically mean better UV protection. UV protection is a function of the lens coating, not the tint depth. A clear lens with UV400 coating provides full protection; a dark lens without it does not.
Blue Light Filtering
What It Does
Blue light filtering lenses reduce the transmission of high-energy visible (HEV) blue light — the wavelength most associated with digital screens, LED lighting, and artificial indoor environments. Blue light filtering coatings typically block between 20% and 40% of blue light, depending on the specification.
Who Benefits Most
Those who spend many hours per day in front of screens — computers, smartphones, tablets — may benefit from blue light filtering lenses. Reported benefits include reduced eye strain, improved contrast in screen environments, and better sleep quality when worn in the evening hours.
What the Research Says
The evidence on blue light filtering is still evolving. While many wearers report subjective improvements in comfort, the scientific consensus on long-term eye health benefits is not yet definitive. That said, for heavy screen users, the comfort benefits alone make blue light filtering a worthwhile consideration.
Scratch-Resistant and Hard Coatings
Most premium lenses include a scratch-resistant hard coating as standard. This does not make lenses scratch-proof, but significantly extends their lifespan under normal daily use. Always store your glasses in a hard case and clean with a microfibre cloth to maximise lens longevity.
Combining Coatings for Maximum Performance
The best lens specifications combine multiple coatings: UV400 protection as a baseline, AR coating for visual clarity, and optionally blue light filtering for screen-heavy lifestyles. Premium lens manufacturers integrate these coatings seamlessly, with no compromise to optical clarity.
