Sunglasses Buying Guides
The decisions that actually matter — lens type, tint, UV, fit — explained without the jargon or the hype.
Most sunglasses confusion comes down to a handful of decisions: polarized or not, which lens color, whether UV400 is doing what you think, and how to match a frame to your use. These guides answer those, with sources, so you can spend confidently.
Start with polarized vs non-polarizedif you're not sure whether you want polarized at all — it's the decision that changes everything else. Then use the category roundups (fishing, cycling, golf) to turn the decision into a pick.
