What Is TR90 Eyewear? A Guide to Lightweight and Flexible Frames

When choosing eyewear frames, material can have a major impact on comfort, flexibility, durability, and overall design. For optical retailers, understanding different frame materials can also make it easier to build a balanced collection that meets a variety of customer needs.

One material that has become widely used in modern eyewear is TR90.

Known for its lightweight construction and flexibility, TR90 is commonly used for frames designed for everyday comfort. Its material characteristics also make it suitable for a variety of frame shapes and designs.

But what exactly is TR90, and why is it used in eyewear?

In this guide, we’ll explore the characteristics of TR90 eyewear, its advantages, how it compares with other frame materials, and what optical retailers should consider when adding TR90 frames to their collections.

 

What Is TR90?

TR90 is a thermoplastic material used in a variety of applications, including eyewear frames. It is valued in eyewear manufacturing for its combination of light weight, flexibility, and resistance to everyday use.

Unlike traditional rigid plastic frames, TR90 can provide a degree of flexibility while maintaining the structure needed for an eyewear frame.

This combination makes TR90 particularly suitable for lightweight, everyday eyewear.

 

Why Is TR90 Used for Eyewear Frames?

The popularity of TR90 comes largely from the combination of properties it can offer in a single frame.

1. Lightweight Construction

One of the most recognizable characteristics of TR90 eyewear is its lightweight feel.

For customers who wear glasses throughout the day, frame weight can have a noticeable effect on overall comfort. Lightweight frames can feel less cumbersome during extended wear and can be particularly appealing to customers who prefer a minimal feel.

For optical retailers, TR90 provides an option for customers who prioritize lightweight everyday eyewear.

2. Flexibility

TR90 is also known for its flexibility.

A certain degree of flexibility can be useful in everyday eyewear because frames are exposed to repeated handling, adjustment, and movement during normal use.

Rather than being completely rigid, TR90 frames can accommodate a degree of movement while maintaining their overall structure.

This makes flexibility one of the key characteristics to consider when evaluating TR90 frames.

3. Everyday Comfort

The combination of low weight and flexibility can contribute to a comfortable wearing experience.

For customers who wear glasses for many hours a day, a lightweight frame can be an important consideration.

This is particularly relevant for optical retailers building collections around everyday eyewear, where comfort and practicality are often major purchasing factors.

4. Heat Resistance

TR90 also has useful heat-resistant characteristics.

This can be particularly relevant during lens installation, where controlled heating may be part of the fitting process. The material's characteristics can help reduce the risk of becoming brittle during appropriate heating and lens installation procedures.

As always, optical professionals should follow appropriate equipment settings and handling procedures for the specific frame.

5. Design Versatility

Although TR90 is often associated with practical and lightweight eyewear, it is not limited to simple designs.

The material can be used to create a variety of frame shapes, sizes, and styles. This allows manufacturers and optical retailers to incorporate lightweight construction into collections with different aesthetic directions.

 

What Are the Benefits of TR90 Eyewear?

For customers, TR90 frames can offer several practical advantages.

Lightweight Feel

TR90 is a strong option for customers who prefer frames that feel light on the face.

Flexible Construction

Its flexibility can make it suitable for everyday frames that need to accommodate normal handling and movement.

Comfortable for Extended Wear

Lightweight construction can be particularly appealing for customers who wear their glasses throughout the day.

Versatile Frame Design

TR90 can be used across a range of frame shapes and styles, making it useful for different optical collections.

Practical Everyday Positioning

TR90 can work particularly well for collections focused on everyday wear, comfort, and lightweight construction.

 

TR90 vs. Traditional Plastic Frames

One reason optical professionals consider TR90 is its combination of properties.

Traditional plastic frames can provide excellent design flexibility and a wide range of colors and finishes, but their characteristics can vary significantly depending on the specific material and construction.

TR90 is often selected when lightweight construction and flexibility are priorities.

Rather than viewing TR90 as a replacement for every other frame material, it is more useful to think of it as another option within a broader eyewear material portfolio.

Different materials can serve different customer needs and product positions.

 

TR90 vs. Acetate

TR90 and acetate are both popular eyewear materials, but they tend to be associated with different design priorities.

TR90 is particularly well suited to:

• Lightweight everyday eyewear

• Flexible frame designs

• Comfort-focused collections

• Customers who prefer a minimal feel

Acetate is often chosen for:

• Premium-looking frames

• Rich colors and patterns

• Distinctive designs

• Fashion-focused eyewear and sunglasses

For optical retailers, carrying both materials can create a more diverse collection.

TR90 can provide lightweight everyday options, while acetate can add premium aesthetics and stronger visual character.

Is TR90 Good for Everyday Eyewear?

For many everyday eyewear applications, TR90 can be a practical material choice.

Its combination of low weight and flexibility makes it well suited to frames designed for regular wear.

However, the overall performance of an eyewear frame depends on more than material alone. Frame construction, thickness, hinges, finishing, lens shape, and manufacturing quality can all affect the final wearing experience.

For optical retailers, it is therefore useful to evaluate the complete frame rather than choosing a material based on a single characteristic.

 

What Should Optical Retailers Consider When Choosing TR90 Frames?

When selecting TR90 eyewear for an optical collection, retailers should consider several factors.

Customer Comfort

If your customers frequently wear glasses for long periods, lightweight frames can be an attractive addition to your assortment.

Frame Variety

TR90 can be used across different shapes and designs. A well-balanced collection should still include a variety of frame styles to accommodate different customer preferences.

Product Positioning

TR90 frames can work well as everyday, lightweight, and comfort-focused products. Consider how they complement your premium acetate or metal collections.

Construction Quality

Material is only one part of frame performance. Pay attention to frame construction, hinges, finishing, and overall manufacturing quality when evaluating wholesale eyewear.

Customer Demographics

Different customers prioritize different characteristics. Some may value lightweight comfort, while others may prioritize premium materials, distinctive patterns, or a particular style.

A diverse material strategy can help an optical retailer serve a broader customer base.

 

TR90 Eyewear at Mutual Optical

At Mutual Optical, TR90 is used across several designs within the YouMe collection, with each series taking a slightly different approach to frame construction.

The YouMe 31 Series uses TR90 throughout the frame and incorporates a stainless steel pin at the end of the temple. The combination is designed to provide lightweight construction and flexibility, while the temple pin allows adjustment based on individual fitting needs.

The YouMe 32 Series combines a TR90 front with propionate temples and a temple pin. This construction provides a balance between the characteristics of TR90 and a more cost-conscious temple material.

The YouMe 61 Series combines a TR90 frame front with stainless steel temples featuring a multi-layer plating process, bringing together lightweight frame construction with a more refined metal finish.

These different designs demonstrate how the same core material can be used in different ways to create eyewear for different product positions and customer preferences.
