Serengeti Sunglasses - Black - Rectangle

The photochromatic lenses adapt to changing UV light, making them versatile. However, the filter category three tint might be too dark for very low-light indoor environments. They are best suited for outdoor use where light intensity varies.

Use a soft, microfiber cloth specifically designed for eyewear. For dirtier lenses, rinse with cool water and a tiny amount of mild soap, then gently dry with the cloth. Avoid paper products or abrasive cleaners.

This refers to the standard eyewear sizing: 53mm is the lens width, 20mm is the bridge width, and 145mm is the temple length (from the hinge to the end of the arm).

These sunglasses are designed for UV protection from the sun. They do not specifically block blue light from digital screens, although the polarized lenses can reduce screen glare.

The lenses are integrated into the frame. While not designed for user replacement, a professional optician might be able to assist with lens replacement if needed, though this is not a standard feature.

Polarized lenses reduce glare reflecting off surfaces like water, snow, and roads. This improves visual comfort, clarity, and reduces eye strain, making them excellent for driving and water activities.

The adjustment time can vary depending on temperature and UV intensity. Typically, they darken within 30 seconds to a minute in bright sunlight and clear up within a few minutes when moving indoors or into shade.

Photochromatic lenses adjust based on UV light, not visible light. They may take a few moments to darken or clear, especially in cars where windshields block some UV rays. Ensure you are in direct sunlight for optimal performance.

Adjust the temple arms slightly for a better fit. If the issue persists, consider consulting an optician for professional adjustment or seeking alternative eyewear solutions.

Ensure the polarized lenses are correctly oriented. While polarized lenses reduce glare, very specific angles of glare can sometimes still be perceived. Clean the lenses thoroughly as smudges can sometimes mimic glare.

Plastic frames can become stiff if exposed to extreme temperatures. Try warming them slightly with your hands before attempting minor adjustments. Avoid forcing the frame.
