Calvin Klein Mens Square Sunglasses - Black/Violet - One Size

UV 400 protection means the lenses block all light rays with wavelengths up to 400 nanometers, effectively blocking 100% of harmful UVA and UVB rays.

The square style is generally versatile, but as a one-size-fits-all product, the fit may vary. We recommend checking measurements if available or trying them on if possible.

Always use a clean, soft microfiber cloth. Avoid paper towels or rough fabrics. If needed, a specialized lens cleaning spray can be used sparingly.

The lenses are made of polycarbonate, known for its impact resistance and lightweight properties.

The frames are made of plastic and are generally designed for comfort. However, individual sensitivities can vary. If irritation occurs, discontinue use and consult a physician.

Lenses are typically not user-replaceable for this model. Significant damage may require replacement of the entire unit.

Typically, sunglasses come with the item itself. A protective case may or may not be included; please check the product packaging or listing details.

While designed as one-size-fits-all, minor adjustments can sometimes be made by a professional optician. Avoid attempting to bend the frames significantly yourself, as this may cause breakage.

Use a clean microfiber cloth specifically designed for eyewear. For stubborn smudges, a small amount of lens cleaning solution can be used sparingly, followed by gentle wiping.

Minor surface scratches may be unavoidable with regular use. For significant scratches that impair vision, lens replacement may be necessary, though this is not typically a user-serviceable part.
