More than ever, sunglasses are being worn as a fashion accessory. From day to night, sunglasses can be seen on celebrities, influencers and the average fashionista. But sunglasses are more than just a fashion accessory; they play a crucial role in protecting our eyes from harmful UV rays and maintaining overall eye health.
UV protection
The primary function of sunglasses is to shield our eyes from the harmful effects of ultraviolet (UV) rays emitted by the sun. Prolonged exposure to UV rays can lead to various eye problems, including cataracts, macular degeneration, and photokeratitis. High quality sunglasses with quality lenses block 100% of both UVA and UVB rays, providing a crucial barrier against these harmful elements.
Not all sunglasses are created equal. When considering sunglasses as a means of eye protection, it is essential to ensure the lenses are high quality and protect against UV rays. Depending on your lifestyle, you may also want to consider different lenses or coatings.
Polarized lenses
Polarized lenses reduce glare caused by sunlight reflecting off surfaces like water, snow, and pavement. This feature enhances visual clarity, making them ideal for activities like driving, skiing, or spending time near water.
Photochromic lenses
Photochromic lenses automatically adjust their tint based on the level of UV light exposure. They darken in bright sunlight and lighten in low-light conditions, providing versatility for various environments.
Mirrored lenses
Mirrored lenses have a reflective coating that reduces the amount of light entering the eyes. They are stylish and can be particularly beneficial in high-glare situations.
Gradient lenses
Gradient lenses are darker at the top and gradually lighten towards the bottom. They provide sun protection while allowing for a clear view of objects in the lower field of vision, making them suitable for activities like driving.
In addition to lens type, there are also various lens coatings to consider.
Anti-reflective coating: reduces glare and reflections on the back of the lenses, improving clarity and reducing eye strain.
Scratch-resistant coating: protects the lenses from scratches, ensuring durability and maintaining optical quality.
Water-repellent coating: helps repel water droplets, preventing them from obstructing vision during rain or water-related activities.
Finding the right style
Choosing the right style of sunglasses is not only about aesthetics but also about functionality. Consider the shape of your face, the level of coverage you desire, and your personal style. Aviators, wayfarers, cat-eye, and sporty frames are just a few of the many options available.
Sunglasses are a vital accessory for maintaining eye health and protecting against the harmful effects of UV rays. Understanding the different types of lenses, coatings, and finding the right style ensures not only style but also optimal functionality. Remember, the importance of wearing sunglasses extends beyond sunny days – they are a year-round necessity for safeguarding your eyes.
