How does frame material and design matter?

Frames are purpose-built to serve one primary function: supporting the lens and by extension, you, through meticulous and deliberate design. Within this framework, three key elements define exceptional frame quality: material, grip, and coverage. Each facet plays a pivotal role in delivering top-notch performance and protection, all geared towards achieving a singular objective: functioning so seamlessly that they seamlessly blend into your experience.


Let's delve into material as the starting point. As a pair of performance sunglasses for sports, lightweight is a key aspect. Be it a long-distance run or navigating unfamiliar terrain on a mountain bike, your sport sunglasses should enhance rather than distract from your activity. The aim is to have frames so lightweight that they vanish from your awareness.

To attain comfortable, featherweight wear, the choice of frame material is pivotal.

Leading the forefront of sports sunglasses frames are those crafted from polycarbonate or similarly robust plastics (e.g. TR90) with exceptional impact resistance. These frames are further enhanced with rubber padding, strategically positioned to provide cushioning where the frame interfaces with the nose and head. Both materials offer exceptional lightness without compromising on durability, and some of the manufacturers have upgraded the material so that it could be floating on seawater.

However, steer clear of metal as a frame material for sports sunglasses. While it may be appealing for casual wear, metal frames lack the resilience needed for rigorous activities and provide inadequate peripheral coverage against the sun.


Grip assumes a critical role in maintaining your sunglasses' position, allowing you to focus on your game or activity. This holds especially true for sport prescription sunglasses, where any frame adjustment translates into a shift in your vision. Rubber nose pads and temple tips aid in keeping frames secure through every move, impact, or jostle. Even under high-intensity impact, hydrophilic rubber on the nose bridge and temples enhances grip as perspiration and activity level rise.


Lastly, let's explore coverage. Its significance lies in shielding against debris and the elements. Two primary factors dictate the coverage level for your prescription glasses: frame shape and lens height. Frame shape is a crucial consideration, with various shapes serving distinct purposes.
