Grilamid is a specialized thermoplastic material used widely in the eyewear industry. It belongs to the nylon family of plastics (polyamides) and is known for its extreme lightness, high flexibility, and excellent resistance to heat and chemicals. It is a highly durable material often used for safety glasses and sports frames.
read more about grilamid in eyeglass frames ...Grilamid is a top choice for sports frames because it can withstand high impact without snapping. It is incredibly light, which keeps the frames comfortable during physical activity. The material also maintains its shape well in hot conditions and resists damage from sweat, sunscreen, and oils.
Grilamid is far superior to standard acrylic or polycarbonate plastic frames. It is much more flexible, allowing the frame to bend significantly before breaking. It is also lighter and resists breakdown from UV light and chemicals better than most other plastics.
Grilamid frames can be adjusted slightly by an optician, often by using heat. The adjustment range is smaller than what is possible with metal frames. Since Grilamid is designed to hold its shape well, people often buy them pre-sized to fit closely to the head.
Grilamid is a rigid plastic used only for spectacle frames and cannot be used in soft contact lenses. Frames are still relevant to contact lens wearers. Choosing a lightweight, durable Grilamid frame as a backup allows your eyes to rest from contact lens wear and provides necessary vision correction on days when contacts cannot be worn.
Yes, Grilamid is inert and generally considered a hypoallergenic material for skin contact.
No, Grilamid is known for its high impact strength and flexibility, making it very resistant to breaking under stress.
Grilamid frames are typically lighter than titanium, providing an exceptionally light feel.
Grilamid is a high-performance polyamide used in sports eyewear. If you notice the frame becoming brittle or "chalky" after years of use, the UV stabilizers may have degraded. Replace the frames to ensure they provide adequate impact protection during physical activity.
