How to choose driving sunglasses?

Pay attention to the color of your sunglasses.

Driving at night should try to avoid tan, green, and gray sunglasses. Tan sunglasses filter out most of the UV rays, which can relax your eyes but can make you sleepy. Wearing green sunglasses will directly change the red light into black, affecting our judgment of traffic lights, which is a great safety hazard. Grey sunglasses, on the other hand, have low light transmittance, which reduces our line of sight and affects our view of the road.

The frame of polarized driving sunglasses

You should choose light alloy material and polymer material with memory, super toughness, collision resistance and wear resistance, low friction coefficient characteristics. It can effectively prevent the damage to the eyes and face caused by the friction of the broken lens frame during use. The work of the frame should be fine. And the grade of pure titanium and aluminum-magnesium alloy is the highest among the metal materials, but most of the metal surface is treated and we can hardly see its material. The weight of pure titanium is 1/2 of ordinary metal, and the weight of aluminum-magnesium alloy is 1/4 of the weight of the commonly used copper frame. High-quality frame solder joints are smooth and even, not rough, with fine workmanship. Ordinary frames have rough solder joints.

Sunglasses with high transmittance lenses.

Wearing sunglasses with a low transmittance can affect the driver's reflexes when driving fast on the highway. In order to ensure that the color of the surrounding environment is not distorted, the edge of the object is clear, and the ability to identify different color signal lights, the relevant transmission ratio is: observe red, yellow, and green traffic signals through the lens, the red signal should be ≥8%; Yellow and green signals should be ≥6%. If the transmission ratio of various traffic signals is too low, the recognition ability of traffic signals will be reduced.

Reflective Sunglasses

Reflective sunglasses are mirror sunglasses that have become popular in recent years. Reflective sunglasses block the sun's rays from above, giving drivers a clearer view of the dashboard. Reflective sunglasses are coated with a thin layer of gradient reflective paint that changes color depth from top to bottom. While driving, it enhances the sunglasses' ability to resist light from above, and from below, and horizontally.
