Have you ever thought about choosing the perfect pair of sunglasses? It’s a question that many of us have asked ourselves at one point. While stylish and trendy sunglasses can be tempting, especially when found at low prices in small shops or on the roadside, it's important to know how to choose them wisely.
Many people are drawn to cheap sunglasses because they look good and feel high quality. However, not all sunglasses are safe. Some may lack proper UV protection, which can actually do more harm than good. In fact, some low-quality lenses may absorb more UV rays instead of blocking them, leading to serious eye damage or even blindness over time.
To help raise awareness about eye safety, experts from the Zhejiang Jiaxing Inspection and Quarantine Bureau shared some key tips for selecting the right sunglasses. They emphasize that while aesthetics play a role in personal preference, the quality of the lenses is crucial. The global standard for lens quality is set by the U.S. Food and Drug Administration (FDA).
According to FDA guidelines, sunglasses should block more than 90% of ultraviolet rays while still allowing sufficient visible light through. Look for labels such as “UV-100PROTECTION†or “UV-400PROTECTION†on the lenses. These labels indicate that the glasses offer full UV protection. If the UV protection is 100%, the label “UV-100PROTECTION†should be clearly marked.
Another important factor is the lens’s optical properties. Sunglasses should not have any prescription-like "power" or diopter. If the lens has a diopter higher than 15%, it may cause dizziness or discomfort when worn.
The lens material must also be durable and able to withstand impact. Materials like plastic (such as propionate or cellulose acetate), resin, or glass should meet certain strength standards to ensure they don’t shatter easily during normal use.
When it comes to color, it’s best to choose a shade that complements your skin tone, face shape, and lifestyle. Classic options like black, brown, and gray are generally safe choices. Gray lenses provide balanced light absorption and don’t distort colors, making them ideal for most environments. Brown lenses, on the other hand, filter out blue light, improving contrast and clarity—especially useful in smoggy or foggy conditions.
Remember, the right pair of sunglasses isn’t just about looking good—it’s about protecting your eyes. Always check for proper UV protection, avoid overly dark lenses, and choose a style that suits your needs and personality. Your eyes will thank you for it.
