When it comes to sunglasses, many people subconsciously think that it is just a kind of fashionable accessories for daily outfits, and one pair of sunglasses will be used in any environment. Actually, there will pose certain safety risks by this kind of behavior, for example, a behavior that is closely related to daily life and occurs every day, that is driving cars to somewhere.
We will encounter all kinds of different weather conditions, sometime the extreme weather like heavy rain, fog, blizzard, hail, sandstorm, typhoon and hurricane. Therefore, it is essential to pay attention to the sunglasses worn while driving, and we recommend to wear sunglasses in different functions when you are in different environments to better protect your eyes, improve the visual clarity and comfort, and to make the driving safer.
So, how to choose the right driving sunglasses in different conditions?
* How to choose the sunglasses for driving in snowy weather?
When choosing sunglasses for snow driving, it is necessary to deal with the strong ultraviolet reflection, usually the reflectivity of snow could reach up to 80%, double than normal weather. The snow weather is also the low-contrast environments, the dazzling light will double and the lenses will fog up. So the requirements of anti-fog, anti-slip and impact resistance also should take into account.
We should choose different colors of lens in different weather conditions, because different color lens are designed to adapt to different light encironments. The functions of sunglasses lens which suit for driving must 100% UV400 protection, infrared filtering, added the high-precision polarizing layers which the polarization effeciency needs larger than 99%, the visible light transmittance need to meet 18%-35%, anti-fog coating and breathable structure which the lens should meet the standard of ISO 18526-4.
According to the experimental data, the amber or copper lenses will increase the obstacle recognition distance by 42% compared to grey lenses.
| Lens Colors |
Applicable Conditions | Functions | Recommend Rates |
| Amber/Copper | Cloudy/Snowy/Foggy | Enhance the yellow-orange spectrumand sharpen the terrain contour | ★★★★★ |
| Rose Gold | Strong Light and Shadow Alternate | Enhance the details in the dark areas and relieve eyes fatigue | ★★★★ |
| Bright Yellow | Blizzard/Visibility Smaller than 100 meters | Ultra-high contrast, limited to low-speed driving |
★★★ |
| Mono Grey | Long-distance Driving on a Clear Snowy Plain |
Restore the true colors | ★★ |
| ⚠ |
Blue Lens/Purple Lens/Dark Green Lens | Distorting the colors of the traffic lights, will increase the rist of snow blindness | × |
Wrapped Structure
1. The side wing shielding of front frame need to exceed 70%.
2. Ensure the horizontal field of view is larger than 120 degrees.
Antiskid Design
1. Silicone or rubber nose pads, which with concave and convex anti-slip patterns will be better.
2. Curved hook design at the end of the temples.
Anti-freezing Materials
1. Grilamid TR90 will be the best material for eyeglasses structure.
2. Polycarbonate lens or TAC polarized lens are more suitable than other materials.
Anti-fog
1. Hydrophobic coating for inner lens.
2. The ventilation groove on top frame will balance the temperature between inside and outside.
Beside the requirements for the lens colors, the materials and shapes of frame structure also have rigid standards.
* How to choose the driving sunglasses in foggy weather?
The core demand of sunglasses when driving in foggy weather is improving the visual contrast and prevent the lenses from adding to the dimness, then to make the vision clearer and increase the safety factors during the driving.
The lens colors and lens coating are the key imprtance for the sunglasses used for driving in the foggy weather conditions. The lenses are coated with multi-layer AR coating could reduce the internal reflection and dashboard refelction effectively.
According to German TÜV certification, the bright yellow lenses increase the road sign recognition distance by up to 40% in foggy weather.
| Lens Colors | Optics Principles | Applicable Weather | Transmittance Rate |
| Bright Yellow | Filter the blue-violet light and enhance the wavelength of red light | Thick-foggy | 70% - 85% |
| Amber | Improve the contrast of orange and yellow objects | Light-foggy | 50% - 65% |
| Light Rose Gold | Balance the color and brightness | Smoggy at night | Larger than 80% |
* How to choose the driving sunglasses at night?
The environment for night driving is more uncontrollable compared to other extreme weather conditions. In addition to the dim light, it is also necessary to deal with the sudden appearance of strong light, the high beams. When driving in the bustling urban areas, drivers will meet the situation of excessive light and various light pollutions interfering with the line of sight.
If we still use the ordinary sunglasses at night when driving, it will reduce the brightness seriously and endanger the safety. So it is really important to choose a professional sunglasses used at night. The certified sunglasses for night driving should meet the standards of EN ISO 12312-7 and ANSI Z80.7.
| Lens Colors | Optics Principles | Applicable Scenarios | Transmittance Rate |
| Professional Bright Yellow Lens | Filter the blue-violet light in dimly lit weather, enhance the yellow-green spectrum |
Highway with opposite high beams | 88% |
| Photochromic Yellow Lens | The lens color will be transparent in dim light condition.
The lens color will turn to yellow in 3-4 seconds when exposed by the car lights. |
A rainy night with ground reflection | 75% - 85% |
| Anti-glare Transparent Lens | Multi-layer AR coating to improve the transmittance rate. |
City at night with strong light pollution |
98% |
