Product Insights
The Cut Forty Square Sunglasses by Spitfire offer optical-grade hand-polished block acetate frames with double barrel hinges and Teflon-coated screws ensuring long-term stability and adjustability, while UV400 distortion-free lenses with anti-reflective coating provide clear vision and full UV protection, but the lack of polarization means horizontal glare reduction is omitted; the acetate frames mold to facial contours for comfort, yet the material warps above 60°C and reacts with perfumes, requiring storage in the included hard case and gentle cleaning; despite premium hardware typically found in higher-priced sunglasses, Spitfire’s brand perception as a cheap fashion brand creates a value gap, and the rigid hinges, though durable, lack self-adjusting flex; lens and frame colors vary, with the Chocolate/Espresso being darker and less saturated.

Spitfire sunglasses are cheap fashion items
I have no experience with them, but from looking at their site I would just say to set your expectations low. They're cheap/affordable fashion sunglasses which don't pretend to be anything more than that.
