Vintage Polarized Photochromic Sunglasses for Men and Women

These stylish outdoor polarized sunglasses are designed to protect your eyes. The frame width measures 63MM, lens height 42MM, temple length 137MM, total frame length 145MM, and nose bridge 20MM. The spring hinge frame is constructed with TR material to withstand damage during outdoor activities, making the sunglasses ultra-light and durable. Comfortable nose pads provide maximum comfort and flexibility.

The photochromic lenses automatically adjust their transmittance by changing color in response to exposure to UV sunlight. Indoors or at night, the lenses are slightly tinted, but they will darken to a sunglass tint when exposed to UV rays. This allows your eyes to adapt to changes in ambient light, reducing visual fatigue and keeping your eyes in the most comfortable state. The photochromic effect is automatic and reversible.

The well-proportioned eyeglass frames are designed to offer comprehensive protection from harmful light coming from different angles. Durable aluminum-magnesium temples (spring legs) provide horizontal flexibility for comfortable wear. These retro-styled polarized sunglasses are suitable for a variety of activities, including hiking, driving, shopping, traveling, photography, fishing, and more. They serve as fashionable accessories for both men and women, making them an excellent year-round choice and a wonderful practical gift for friends and family.

The FEISEDY Photochromic Driving Sunglasses feature a unique lens technology. When exposed to ultraviolet and short-wave visible light in sunlight, the lens color becomes darker, reducing light transmittance. Indoors or in darker environments, the lens transmittance increases, and the color fades back. This automatic and reversible photochromic effect allows your eyes to adapt to changes in ambient light, reducing visual fatigue and providing optimal eye protection.

Key features of these polarized sunglasses include an anti-impact layer that improves lens toughness and impact resistance, preventing scratches and extending lens life. The polarizing layer filters and blocks reflected glare, while providing 100% UV protection for clear and natural vision. These sunglasses are designed for driving and outdoor activities, ensuring a comfortable and enjoyable experience.

The package includes a soft cleaning cloth, a soft glasses bag, the sunglasses themselves, and a polarized text card. It is important to avoid using the sunglasses in high temperatures for extended periods, as this can be detrimental to both your health and the glasses. The sunglasses should be treated carefully to avoid damage and cleaned regularly using soap water or neutral detergent, gently wiping the lenses dry with the included soft cloth. When not in use, the glasses and accessories should be stored in the provided spectacle case.
