The Smith Baseline Sqaure Sunglasses is an ideal pair for those looking to cover an expanded field of view. Offering greater coverage than the similar Baseline Round sunglasses, these Smiths are perfect for when the sun is really shining. The 8 Base Curve of the Baseline provides just enough wrap to protect you from the elements while still looking good. The Baseline Sunglasses feature TLT Carbonic lenses which protect your eyes from harmful UVA/B/C rays and are tough enough to stand up to your everyday routine. Should the included lenses not suit your needs, you'll find that the Baseline lets you interchange different lenses to let you switch out style and function. Constructed in a light TR90 Grilamid frame, these Smith glasses stand up to the rigors of your day to day while ensuring a non-slip fit. When the sun is shining bright, make the Smith Baseline Square Sunglasses your go-to pair.
