The Bio-Resin Raw Material ProcessThe Bio-Resin Raw Material Process is part of our Kick Plastic initiative to reduce our carbon footprint and protect our planet’s waters. Our earth-friendly bio-resin frames are durable and lightweight, and hold their shape under the harshest conditions.
Frame Qualities and Options
Costa offers frames to meet everyone's needs. Customers can choose a frame based on color, hypoallergenic materials, durability, lightness, cost and uniqueness. Each frame offers its own performance advantages and style features for eyewear that fits every occasion.
Co-Injected Nylon Frames
Our nylon frames are tough and durable, with more color options manufactured using the environmentally friendly bio-resin process. TR-90 nylon is a premier material for sports and performance frames as it is resistant to heat and cold. Though it is flexible, it is still durable. Nylon is easly molded into wraparound and other shapes.

Metal Frames provide a different look and feel. We use only the best in metals - marine-grade corrosion-resistant Monel® and lightweight, hypoallergenic titanium.

If mixing it up is your thing, we combine the best of bio-based resin with our corrosion-resistant metals. The combination of materials also allows for more style variations.

Rimless eyeglasses are feather-light because there is simply less nylon frame material sitting on your face. They're generally more comfortable, more streamlined and perfect for a variety of sports.

A] Co-injected Bio-Based Nylon
Our bio-based nylon frame material is tough and durable. As a result, Cost'a co-injected frames offer the best-fit and greatest comfort on the market today.
- Best Fit
- Greatest Comfort
B] Corrosion-Resistant Monel Metal
Monel's super tough, corrosion-resistant alloy is often used in marine applications. If you are on the water a lot, Monel stands up to the challenge.
- Great on the Water
C] Hydrolite Rubber
Hydrolite is our proprietary, hypoallergenic rubber which prevents slippage. We use Hydrolite rubber on comfort spots such as nose pads and temples.
- Prevents Slippage
Titanium is as strong as steel but lighter weight, making these frames perfect for sports. Though titanium is one of the strongest metals, it reverts back to its original shape even after exerting pressure. Titanium is often used in prosthetics because it is hypoallergenic and corrosion-resistant.
- Perfect for Sports
E] Beta Titanium
Beta titanium is a hypoallergenic titanium alloy made by blending titanium with other metals. It is extremely durable and strong, but bends, reducing damage and broken frames.
- Strong but Flexible
- We are the industry leader in this manufacturing process.
- Original bilateral and trilateral styles are created by bonding together two or three distinct colors into one frame.
- Each layer is comprised of solid color bio-resin. The result is a highly durable frame with chip-proof color.
- We offer multiple unique color combinations in both bilateral and trilateral styles.
Our corrosion-resistant, stainless steel flexible hinges keep their shape and fit perfectly.
They come in three types:
- Optical spring
- Five-barrel optical
