"Sunglasses: How to Choose a Quality Eyewear for Eye Health" The quality of sunglasses varies, and opting for cheaper options may harm your eye health. This is because the materials used for making sunglasses don't always meet standards, leading to low-quality lenses. Some sunglasses have plastic lenses with low-quality films, while others are made from regular glass, which can distort your vision over time.   For individuals who frequently face bright sunlight, like when driving during midday, playing sports, or working outdoors, it's essential to select polarized sunglasses. These sunglasses are made with polarized plastic lenses that reduce reflected light, preventing eye strain and cutting glare effectively. Additionally, they reduce glare from roads and help prevent eye fatigue during prolonged sun exposure.   Sunglasses today also come in various tint options suitable for different environments. For instance, when at the beach or in the mountains, sunglasses with a green-gray lens can provide clear and sharp vision even on hazy days. These lenses work like fog lights on a car, enhancing visibility in hazy conditions, and helping you see your surroundings clearly.   Choosing the best sunglasses requires considering several factors:   Lens Material: Look for lenses with a melanin component, as they absorb dangerous light and ensure comfortable vision. Quality sunglasses should absorb 100% of UV-B and UV-A rays without distortion. Lens Color: The most popular lens tint is green-gray since it effectively filters light and causes minimal eye strain. This lens type is suitable for intense sunlight exposure. Brown-yellow lenses may slightly distort colors, but they are perfect for late afternoon or hazy days. Frame Shape and Fit: Opt for sunglasses that suit the shape of your face, ensuring a comfortable fit. They should neither be too tight nor too loose, preventing discomfort and slipping.   How long should you keep your sunglasses? Consider replacing your sunglasses every 2 years. For individuals with prominent cheekbones, avoid oversized sunglasses that cover your cheekbones. If you're unsure about which sunglasses to choose, opt for aviator-style glasses, as they suit almost all face shapes. The most suitable sunglass shape is one that contrasts with your face shape. Sunglasses with brown lenses are suitable for individuals with nearsightedness, while green lenses are preferable for those with farsightedness. Opt for quality over aesthetics when selecting sunglasses, ensuring they offer adequate protection for your eyes. By considering these factors, you can choose sunglasses that not only enhance your style but also provide the best protection for your eyes.
