How to choose sunglasses online

To choose 2nu sunglasses online, start with your main activity, head-size direction and preferred coverage. Then choose the lens family for UV400, glare control and screen checks. Use the Frame Guide to narrow the frame. If fit or pressure is still uncertain, TryOn lets you test the same frame structure in real movement before buying the regular pair.
