Here are a couple of great options for your husband's clear frames: The Oakley Holbrook sunglasses in Matte Sand prizm Black (R1829) would be an excellent choice. The Holbrook is Oakley's iconic and timeless classic style that is perfectly suited for everyday wear. With Oakley's prizm lens technology, he will see clearer and enjoy optimized contrast wherever he goes. Additionally, the Oakley Leffingwell sunglasses in Matte Black prizm Sapphire (R1599) is a fantastic value. The Leffingwell has a slightly smaller and more subtle frame shape but also uses Oakley's prizm lenses for a perfect combination of protection, clarity and eye comfort. Both styles come with Oakley's unbeatable warranty and craftsmanship. Please let me know if you need any other details! I'm happy to help find the perfect pair of shades for your husband.
