TR-90 Prescription Glasses From $1.99
Lightweight, flexible, hypoallergenic — every LensTrove frame is built in TR-90.
TR-90 is a thermoplastic polymer (technically polyamide / nylon) that has become the gold standard for modern prescription frames. It's about 20% lighter than acetate, considerably more flexible (returns to shape after bending), hypoallergenic, and resistant to chemicals and most solvents. Every LensTrove frame is built in TR-90 and starts at $1.99; prescription lenses start at $19.99.
Why TR-90?
- Lightweight — long-day comfort; no pressure marks behind the ears.
- Flexible — won't snap from a side bump; springs back into shape.
- Hypoallergenic — no nickel, no acetate plasticizers.
- Color-stable — pigments are integrated into the polymer, not painted on.
TR-90 vs acetate
Acetate gives a slightly warmer, glossier finish and is more rigid. TR-90 is lighter, more flexible, and significantly more durable — it's why TR-90 is the dominant material in modern lifestyle and athletic frames.

TR-90 frames — FAQs
Is TR-90 better than acetate?
Different, not strictly better. TR-90 is lighter, more flexible, and more durable. Acetate has a glossier finish and a more 'classic' feel in the hand. For everyday wear and active lifestyles, TR-90 wins on comfort and resilience.
Will TR-90 last?
Yes. TR-90 frames typically outlast acetate ones because they flex rather than crack. LensTrove frames are covered by a 1-year warranty against manufacturing defects.
Is TR-90 hypoallergenic?
Yes. TR-90 contains no nickel, latex, or acetate plasticizers — the most common contact allergens in eyewear.
