[Outdoor knowledge] outdoor glasses mirror color depth is pay attention to
According to a study by the North American Eye Care Union, the most suitable lens colors for sunglasses are smoky gray and green. These shades help reduce color sensitivity and provide a more natural visual experience. In contrast, wearing sunglasses in pink, yellow, orange, red, or violet can lead to eye strain, especially under bright sunlight, which may cause blurred vision. As a result, many pilots and drivers have switched to gray and green lenses for better comfort and clarity.
When it comes to choosing outdoor glasses, understanding the characteristics of different lens colors is essential:
1. **Gray Lenses**: These lenses absorb light evenly across all wavelengths, darkening the view without altering colors. They offer a natural, neutral look and are ideal for everyday use.
2. **Brown Lenses**: They filter out blue light, enhancing contrast and sharpness, making them particularly useful in hazy or polluted conditions.
3. **Green Lenses**: These lenses allow maximum green light to pass through while absorbing other wavelengths, providing a cool and comfortable feel, perfect for those who tend to get tired easily.
4. **Blue-Gray Lenses**: Similar to gray lenses, they are also neutral but darker and offer higher visible light absorption, making them great for intense sunlight.
5. **Mercury Lenses**: Featuring a high-density mirror coating, these lenses reflect more light and are ideal for sports and outdoor activities.
6. **Yellow Lenses**: Though not traditional sunglasses, they enhance contrast in low-light situations like dusk or fog. Some people wear them as a fashion statement.
7. **Light Blue or Pink Lenses**: These are mostly decorative and offer limited practical benefits.
The color of the lens only affects how much visible light is absorbed, not its UV protection. UV resistance depends on the material, not the color. For example, some clear resin lenses still block 100% of UV rays.
Progressive lenses, often colorless or lightly tinted, are designed for both indoor and outdoor use. They help reduce glare from overhead sunlight while remaining functional indoors or in a car. These lenses are especially popular among middle-aged women for their stylish appearance.
