Sunglasses are accessories primarily designed to protect the eyes from harmful ultraviolet (UV) rays and bright sunlight. They consist of tinted lenses mounted in frames that sit comfortably on the face. In addition to their protective function, sunglasses also serve as fashionable accessories, enhancing one's style and complementing various outfits.

The lenses of sunglasses come in different tints, ranging from dark to light, and may offer various levels of UV protection. Polarized lenses reduce glare from reflective surfaces such as water, snow, and roads, enhancing visual clarity and comfort in bright conditions.

Sunglasses frames are available in a wide array of styles, materials, and colors to suit individual preferences and face shapes. Popular frame styles include aviator, wayfarer, round, square, and cat-eye, among others. Frames can be made of materials like plastic, metal, acetate, or wood, each offering different looks and levels of durability.

Whether worn for outdoor activities like driving, sports, or beach outings, or simply as a fashion accessory, sunglasses are a practical and stylish addition to any wardrobe. They not only protect the eyes from UV damage but also add a touch of sophistication or flair to any ensemble, making them a timeless accessory for both practicality and fashion.
