PEEK (Polyether Ether Ketone) frames are spectacle frames made from a high-performance thermoplastic polymer. PEEK is known for its exceptional strength stiffness heat resistance and excellent chemical resistance. It is often used in specialized industries like aerospace and medical devices due to its reliable qualities.

PEEK maintains its shape even at high temperatures and resists damage from solvents making it a good choice for industrial or specialized safety glasses. It is also lightweight and robust.
PEEK is technically superior to acetate in strength heat resistance and chemical stability. Acetate is valued for its color and pattern depth but PEEK is valued for its performance. PEEK is typically stronger and more rigid than standard acetate frames.
The main drawback of PEEK is the cost and limited color options. The material is expensive to manufacture making the final frames more costly. Since PEEK is a performance plastic, it does not hold the variety of colors and deep patterns found in acetate frames.
PEEK is a rigid, high-performance plastic used only for spectacle frames, it cannot be used in soft contact lenses. Frames are still relevant to contact lens wearers. Choosing comfortable, durable PEEK glasses 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, PEEK is widely used in medical and surgical implants due to its stability, strength, and biocompatibility.
Yes, PEEK is a thermoplastic and is recyclable, though its high cost means manufacturers usually try to reuse any scrap material.
Yes, PEEK is generally heavier than high-grade titanium, but its strength allows for very thin, lightweight designs.
Because PEEK is exceptionally biocompatible, it is an ideal frame material for patients with severe multiple chemical sensitivities. If your current plastic frames cause chronic skin inflammation, ask your optician about PEEK-based eyewear.
