Lens Features

Contrast enhancement

To begin, let's delve into the realm of contrast and its underlying purpose. Contrast serves to deepen both shadows and the brightest areas, imparting greater dimension to visuals. This augmentation ensures that intricate details within shadows remain perceptible, enabling swift decision-making. One avenue for bolstering contrast enhancement involves opting for tinted lenses over conventional gray lenses. For instance, during activities like cycling on a paved road, the presence of potholes, roadside debris, and cracks pose potential hazards. Embracing a lighter rose-copper tinted lens empowers you to identify uneven road conditions promptly, averting potential mishaps. Indeed, contrast enhancement proves to be a valuable ally in such scenarios.

Lens materials

Nylon Lenses

Known for being lightweight and flexible.

Offer good impact resistance, though not as high as polycarbonate.

Have a higher Abbe value, which means they have less chromatic aberration and better optical clarity compared to polycarbonate.

Tend to be more expensive than polycarbonate lenses.

Polycarbonate Lenses

Recognized for their high impact resistance and are often used in sports eyewear and children's glasses.

Provide significant UV protection and are also lightweight.

Have a lower Abbe value than nylon, which can result in more chromatic aberration.

Generally more cost-effective than nylon lenses.

When choosing between nylon and polycarbonate lenses, consider the level of impact resistance needed, the importance of optical clarity, and your budget. Polycarbonate lenses might be the go-to for high-impact activities and cost savings, while nylon lenses could be preferred for better clarity and less visual distortion.

Lens coating

Sport sunglasses have become more than just a fashion accessory; they are now essential gear for athletes and outdoor enthusiasts. To enhance their functionality and performance, many sport sunglasses come with various lens coatings that provide distinct advantages. Here are some common lens coating features and their associated benefits:

Hydrophobic Coating

Hydrophobic coating is a very basic type of coating. It weakens the surface tension between the lens and water drops, which means that sweats or water drops would slide off the lens. It also means that sweats or water would not spread out the surface of the lens.


Anti-oil Coating

Anti-oil coating is more advance than hydrophobic coating. It repels oil and water, preventing smudges and fingerprints from sticking to the lens surface.

Backside Anti-Reflective Coating:

Glare from the sun, water, or reflective surfaces can be distracting and harmful. Anti-reflective coating minimizes these distractions for enhanced visual comfort.

Saltwater Resistance Coating

Saltwater resistance coating protects the lens from the corrosive effects of saltwater and other harsh elements. Exposure to saltwater can damage lenses over time. Saltwater resistance coating prolongs the lifespan of the lenses, making the sunglasses suitable for water sports and coastal activities.

Scratch Resistance Coating:

Scratch resistance coating adds a layer of protection to the lens, making it more resistant to minor scratches and abrasions.

Incorporating these lens coating features into sport sunglasses enhances their overall quality and user experience. Each coating addresses specific challenges faced during outdoor activities, making the sunglasses more functional, durable, and user-friendly. When choosing sport sunglasses, considering the lens coating features and their associated benefits is crucial to ensuring optimal performance and enjoyment
