Sunglasses are not tech, but they are gear, and in Queensland they are gear you use more days than you do not. SHADE are made just down the coast at Tugun, which earns them a look.
SHADE Eyewear is an Australian brand based at Tugun on the Gold Coast. The local angle is not just a nice story, it means the product is designed for the conditions it is actually sold into, which is more than can be said for a lot of eyewear that lands here.
The real test
Glare off a car bonnet at three in the afternoon, a sideline at a kids' rugby league game with no shade anywhere, and heat that warps a cheap frame if you leave it on a dashboard. Most sunglasses are fine on day one. The ones worth writing about are fine in February.
Survival is the other half of it. A pair that lives in a family car is not being cared for, it is being used, and that is the honest condition to judge them in.
