Which sunglasses are best for driving, polarized sunglasses or non-polarized sunglasses?
Polarized and non-polarized sunglasses are the same in the ability to protect against ultraviolet rays. But when you work as a driver, in addition to the front of the sun, sometimes there are highway road reflective lights, other car body reflective lights, and so on. Glare will make people's eyes uncomfortable and fatigue, and affect the clarity of vision, stimulating the eyes. Polaroid lenses can filter out light from different angles, so when you driving, is best to wear polarized sunglasses.
What Are the Advantages of High-Index Lenses?
In this section, we will show you the advantages of high-index lenses.
- Thanks to the slim shape and narrow edges, high index lenses offer wearers the flexibility to choose from a wide array of fashion-forward frames. Their size means that they can be easily paired with sleek metal frames or incorporated into rimless eyewear for an attractive barely-there look.
- High index lenses are more comfortable for extended use because they are lighter than the traditional counterparts.
- High index lenses are available with many of the same options as traditional lenses. For example, they can be either single-vision or progressive.
- For users with strong prescriptions, high index lenses mean no bulky, bottle-glasses appearance. This can reduce the unwanted bug-eye look traditionally associated with very thick lenses.
However, there are some negative voices of high index lenses.
The working principle of driving glasses
The driving glasses are designed according to the polarized angle and radian of the lens and the principle of precision optics. It can only let the beneficial light pass through, and other light sources, like strong sunlight, car headlights, and other light sources are filtered, to eliminate the interference of external light, and avoid the appearance of eye-catching, dazzling, and other situations. That's basically how the driver glasses are designed.
General glasses material has plastic and metal two categories. Because the children's glasses degrees change faster, from the economic point of view, choosing plastic material is more affordable. And children love to move, they do not pay much attention to pick up and put on glasses. Choosing metal material is easy to distort, affecting the normal wearing. The material of the lens should be light and thin. The transmittance and refractive index should be high, and it should be wear-resistant and not easy to break.
Different types of nose pads for glasses
The fixed nose pad is usually used on the plate frame. The nose pad and the frame form an organic whole. The maintenance is more convenient, unlike the movable type that should often twist a screw. It is not easy to hide dirt and dirt. But the disadvantage is that the angle of the nose pad can not be adjusted, and it can not fit the bridge of the nose greatly. The movable nose pad can be automatically adjusted up and down according to the shape of the bridge of the nose to ensure that the compression part of the bridge of the nose is evenly stressed and the local pressure is reduced. But the disadvantage is to often check the tightness of the screw, but often scrub clean. The silicone material usually used in the nose pad is easy to yellow after a long time, which affects the appearance.
How polarized glasses can help you drive
The most important thing about polarized sunglasses is that they can be a good helper when you drive. When sunlight hits your eyes at an awkward angle, these sunglasses will save your life and save you from potential accidents. Polarized glasses can filter out the sunlight reflected from objects such as roads, snow, water, and other objects. It helps to neutralize the effects of reflected sunlight. Polarized sunglasses bring you an incredibly safe driving experience, with almost no interference and no harm to your eyes.
At night, glare and embarrassing lights are everywhere on the road, especially because random drivers come from the opposite side. Some of these driving high beams may disrupt your vision and cause potential accidents. Polarized sunglasses help reduce glare and save your life. Polarized lenses hardly reflect.
What Are Blue Light Glasses?
Blue light glasses limit exposure to blue light. Additionally, blue light blocking lenses also include non-glare protection. Blue light can be found in cell phones, tablets, computers, some light bulbs, and sunshine. And this particular wavelength of blue light can damage your retina, which can even lead to vision impairment.
However, blue light glasses can filter the harmful ultraviolet rays and reduce the potential damage to your eyes, and may improve symptoms of computer vision syndrome. Even if you do not need a pair of prescription glasses, you should consider a pair of blue light glasses because there are many benefits to them. Hence, in the following section, we will show you the benefits of blue light glasses.
