Saint Laurent Black Square Unisex Sunglasses SL M157 001 47

Saint Laurent Black Square Unisex Sunglasses SL M157 001 47 is catalogued as 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. Add delivery to the cheapest price and you will see whether it is genuinely the best deal.
