Saint Laurent Unisex Black Square Sunglasses SL280 002

Saint Laurent Unisex Black Square Sunglasses SL280 002 is a unisex pair of sunglasses. Polarised lenses cut glare off roads and water, at the cost of making some phone and dashboard screens look patchy. Worth wearing on any bright day, not just in summer — UV reflects hardest off water, snow and wet roads. Where one is discounted, compare the size and edition rather than the headline alone. Clean with a microfibre cloth and lens spray, never a shirt hem — dust ground into a coating is what scratches lenses. Whoever is cheapest today may not be tomorrow, so it is worth looking again before settling on the best deal.
