What are our frames made of? What are CR-39 lenses? Get the lowdown on some of the materials that we use.

 

FRAMES MADE FROM PLANTS

That’s right, plants. Our frames are made from a natural plant-based plastic called cellulose acetate. This magical material is non-petroleum based and primarily derived from cotton and wood pulp. Cellulose acetate was first discovered in 1865, but it wasn’t until fifteen years later that it would be first used as film for motion pictures and silk-like fabric for clothing. Today, cellulose acetate is the material of choice for eyewear due to its flexible, lightweight and durable qualities. The flexibility of cellulose acetate allows the frames to adapt to the wearer’s face over time. It is also hypoallergenic and less likely to irritate skin.

Fun Fact: Original Lego bricks were made from cellulose acetate in the mid-nineties

 

COLOR SPECTRUM 

Cellulose acetate has high transparency and can be made into an unlimited range of rich colors. Our frames are carved out of large acetate sheets that have been layered with colored plastic to achieve complex colors and patterns from summer turquoise to sahara brown tortoise. Individual pieces are then hand polished and assembled together to create a finished frame. Its unique manufacturing process creates slight pattern and color variations in each frame, making each piece truly one-of-a-kind.

MEET CR-39

This revolutionary, plastic polymer lens is a comfortable, lightweight material that has become widely popular for its superior optical qualities. The hard resin is more impact and scratch resistant and half the weight of glass lenses. Its ability to easily dye allows for a wider range of lens colors, such as this purple gradient lens. Although the material doesn’t have natural, built-in UV protection, our lenses have gone through an extra step to receive a special protective UV400 treatment to protect your eyes from even the tiniest ultraviolet rays that can cause serious eye damage over time.

Fun Fact: Plastic lenses first became popular in the 1970s due to the fashion trend for oversized frames.

UV PROTECTION

Our eyes are just as susceptible to the sun’s harmful UV rays as our skin. Similar to sunblock, lenses should also shield your eyes from harmful solar radiation. Overexposure to UV light can cause cataracts, retinal damage and other future vision problems. Our lenses are coated with an invisible dye that block 100% of UV rays. Remember to always wear sunglasses that offer UV protection whenever you are in the sun!

 

MIRROR LENSES

Mirror coatings, also known as flash coatings, are highly reflective coatings applied to the front surface of lenses to reduce the amount of light entering the eye. These lenses are especially good to have for snow activities or other very bright conditions. Today, you can find mirror coating in almost any color.

 

GRADIENT LENSES 

These tinted lenses start by being darkest at the top, gradually fading to a lighter color on the bottom. Gradient lenses are perfect for driving; they protect your eyes from sunlight but also allow light through the bottom half of the lens so you can see the dashboard clearly. These lenses are now offered in a wide range of colors, with some gradients fading two separate colors.
