Our Take
Polarized sunglasses are one of the best value buys on AliExpress. These classic square frames use genuinely polarized lenses (verifiable by holding them at a 90° angle to any LCD screen — the display will turn dark). UV400 protection blocks 100% of UVA and UVB rays.
The frame is TR90 — a lightweight, flexible nylon that is nearly impossible to snap under normal use. Hinges are spring-loaded, allowing the temples to flex outward slightly for a more comfortable fit on wider heads. The lenses are TAC (Tri-Acetate Cellulose), which is the standard polarization material — not as scratch-resistant as glass but lighter and more impact-resistant.
At under £4, these are essentially disposable sunglasses that perform like £30-40 branded pairs. We sell over a thousand per year and the return rate is negligible. Available in black, matte black, tortoiseshell, and several colour lens variants.
Why We Picked It
Over 1,400 units sold with almost no returns. Genuine polarization at this price is remarkable. The TR90 frames survive being sat on, thrown in bags, and generally abused — which is exactly how most people treat sub-£5 sunglasses.
