What are polarized lenses for?
Polarized lenses contain a layer of polarizing plates in which molecular chains form a light-grating structure in which dichromatic pigments, which absorb polarized light, are evenly distributed. A beam of light is absorbed when it vibrates in the same direction as the bars of the molecular chain of the polarized lens. The grating direction formed by the molecular chain of the polarizer is the axial direction of the polarizer, which is generally horizontal. When polarized lenses are worn, they absorb all the light that vibrates horizontally, thus absorbing the glare and preventing it from reaching the eyes.
What should drivers notice when wearing polarized glasses?
Many drivers like to wear polarized lenses. Indeed, the polarized lens can reduce strong light, eliminate glare, so that the line of sight is natural and soft, but the polarized lens is more suitable for fishing, skiing, and other large areas of the reflective environment. Drivers sometimes have to face the tunnel and another dark scene, the polarized lens is easy to make people suddenly feel dark at the moment. In addition, polarized lenses can make LCD screens and LED traffic lights dim. Therefore, when choosing polarizers, it is best to choose good quality optics, and when going through the tunnel, it is best to take off your glasses ahead of time and blink a lot. Before wearing the driver polarizing lens, try it on and observe whether the polarizing film of the lens is smooth. If the polarizing film is uneven, there will be inflow in the imaging, which may lead to visual fatigue and migraine.
Advantages of aspheric lenses
In reality, aspheric lenses were originally born to improve the marginalized optical properties of spherical lenses. The aspheric lens with special coating treatment has perfect visual performance, with a clearer, more comfortable visual effect. You can hardly feel the presence of aspheric lenses when you put them on. So you can enjoy the ease brought by aspheric lenses. They are more natural and more realistic, having less visual distortion. The aspheric lens can be designed with a flatter base arc, which not only makes the appearance beautiful but reduces the peripheral magnification so that when others look at the eyes of the people who wear glasses, the size will not change much.

If you are wearing glasses for the first time or if your prescription has changed significantly, you may be prone to this effect.
Multiple lens power: if you have changed to a multiple lens power of glasses like bifocal glasses, varifocal glasses, it may be difficult to adapt in a short time. So, this change will lead to some problems such as headaches.
Poorly fitted frames: as for the issue of new glasses headaches, if you glasses fit too snugly across your nose or cause pressure behind your ears, you may get a headache. So, when purchasing a new pair of glasses, selecting a fitted one is important.
