When considering materials for AR/AI glasses, both ABS + PC (Acrylonitrile Butadiene Styrene + Polycarbonate) and TR90 have unique properties. Here's a comparison of the two:

ABS + PC

Advantages:

• Durability: Strong and impact-resistant, making it suitable for protective eyewear.
• Lightweight: Offers a good strength-to-weight ratio, enhancing comfort.
• Cost-Effective: Generally more affordable than some advanced materials.
• Moldability: Easy to mold into complex shapes, suitable for intricate designs.

Disadvantages:

• Less Flexibility: While strong, it may not be as flexible as TR90.
• Heat Resistance: Lower heat resistance compared to TR90, which can affect longevity.

TR90

Advantages:

• Flexibility: Highly flexible and can withstand bending without breaking.
• Lightweight: Extremely light, enhancing comfort for prolonged use.
• Heat Resistance: Better heat resistance, making it suitable for various environments.
• Skin-Friendly: Generally hypoallergenic, reducing irritation for users.

Disadvantages:

• Cost: Typically more expensive than ABS + PC.
• Moldability: May be less versatile in molding complex designs compared to ABS + PC.

Conclusion

The choice between ABS + PC and TR90 for AR/AI glasses depends on specific design goals, budget, and user comfort preferences. TR90 is often favored for high-end applications due to its flexibility and comfort, while ABS + PC may be suitable for more cost-sensitive designs.
