Sunglasses, also known as shades or sunnies, are eyewear designed to protect the eyes from the sun's harmful ultraviolet (UV) rays and high-intensity light. They are typically worn outdoors, particularly in bright sunlight, to reduce glare and improve visual comfort. In addition to their protective function, sunglasses have become a fashion accessory, allowing people to express their personal style.

Here are some key points about sunglasses:

1. UV Protection: One of the primary purposes of sunglasses is to shield the eyes from harmful UV radiation. When purchasing sunglasses, it's important to look for a pair that provides 100% UV protection or blocks both UVA and UVB rays.

2. Lens Types: Sunglasses come with different types of lenses to suit various needs. Some common lens types include:

   - Non-Polarized Lenses: These lenses reduce the amount of light that reaches the eyes but don't eliminate glare.

   - Polarized Lenses: These lenses contain a special filter that blocks intense reflected light, reducing glare and improving visual clarity. They are particularly useful for activities like driving, fishing, or skiing.

   - Mirrored Lenses: These lenses have a reflective coating that reduces the amount of light entering the eyes. They are popular for outdoor sports and fashion purposes.

3. Lens Colors: Sunglasses are available in a variety of lens colors, and each color has different effects on vision and light transmission. Some common lens colors include gray, brown, green, and yellow. The choice of color often depends on personal preference and the intended use of the sunglasses.

4. Frame Styles: Sunglasses frames come in numerous shapes, sizes, and materials, allowing individuals to find a style that suits their face shape and fashion taste. Some popular frame styles include aviator, wayfarer, cat-eye, round, and rectangular frames.

5. Prescription Sunglasses: People who require vision correction can opt for prescription sunglasses. These sunglasses have prescription lenses that provide both sun protection and vision correction.

6. Care and Maintenance: To ensure that sunglasses last longer and provide optimal protection, it's essential to take care of them. Cleaning the lenses with a microfiber cloth and storing them in a protective case when not in use can help prevent scratches and damage.

Remember, while sunglasses offer protection against UV rays, they should not be considered a substitute for protective measures like wide-brimmed hats and sunscreen.
