Sunglasses are usually seen as a fashionable accessory, but their role is much more important than this. They not only promote style, but also contribute significantly to the safety of the eyes. Sunglasses protect the eyes from harmful ultraviolet (UV) rays, which can cause severe eye problems such as cataract, macular degeneration and cancer of the eyelids. High quality sunglasses are capable of preventing 99% to 100% UVA and UVB rays, providing prevention of sun radiation.
Sunglasses also reduce the dazzle. Especially from reflective surfaces like water, ice and roads, causing the clarity and comfort of vision during external activities. This makes them important not only stylish, but also for the safety of the eyes. Let's know how sunglasses provide protection to your eyes and how to choose the right glasses.
1. 100% UV Security: Always choose glasses that provide 100% UVA and UVB protection. It is most important for protecting your eyes from the harmful radiation of the sun.
2. Quality of Lens: Choose scratch-resistant and optically right lenses. High quality materials such as polycarbonate or glass give better durability and clarity.
3. Polarized Lens: If you spend most of the time out, especially when driving water or vehicle, then the polarized lenses help reduce the dazzle.
4. Certification Label: Ensure that your glasses have certification labels like Ansi or CE, which meet security and quality standards.
5. Right Fit: The frame of glasses should be such that fit around the nose and ears, so that it is comfortable and provides maximum protection.
1. Protection from UV rays: Good sunglasses provide protection from 100% UVA and UVB rays, which are harmful to the eyes.
2. Stop eye irritation: Your eyes can also burn with the light of the sun, which is called photocratitis. Sunglasses prevent this, especially when you are near the reflective surfaces like water or ice.
3. Prevention of wind, dust and debris: Sunglasses protect the eyes from environmental elements such as dust, sand and pollen, which reduces the risk of dry eyes and infection.
