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.
Evolution of hard coating technology
The first generation of the use of hard coating technology began in the early 1970s, the quartz material is deposited on the surface of a resin lens under vacuum conditions, form a very hard anti-wear film. However, due to the mismatch between the thermal expansion coefficient and the film base material, it is easy to delaminate and crack the film. Instead, it forms the mottle on the surface of the lens, and the effect is not optimal.
The second generation of hard coating technology is the use of the 1980s. The surface of the resin sheet is coated with a material with high hardness and not easy to be brittle and cracked by an immersion process. At this time, anti-reflection coating lenses had appeared and gained the recognition of consumers, but the mismatch between adding hard coating and anti-reflection coating still caused serious lens wear.
The third generation of hard coating technology was developed in the 1990s, mainly in order to solve the problem of wear resistance after coating resin lenses with an anti-reflection film. The hardened material evolved into a polymer organic matrix material.
Fourth-generation coating technology is dominated by silicon atoms, in which the hardened solution contains both organic substrates. It contains inorganic ultrafine particles, including silicon elements, which make the hard coating not only tough but also hard.

Different Types of Eyeglass Frame Materials
Titanium: as for metal frame material, Titanium is one of the most popular ones. The titanium frame material can be bent and twisted and then come back to its original form. The quality of these frames is durable and reliable for rough use. The Titanium frame material is light.
Flexon: Flexon is a titanium alloy that is composed of around 50% titanium and 50% nickel. Flexon eyeglass frames are extremely flexible and can be twisted or bent to an extreme and can return to their original shape. The flexon frame material is popular among kids' glasses.
Beta titanium: this is an alloy mainly composed of titanium and a small amount of aluminum and vanadium. The beta-titanium has a memory feature and is mostly used in high-quality designer frames. The beta-titanium is toughness and light.
Monel: it is an alloy of nickel and copper. The monel frame material is cheap and discolor.
Beryllium: it is an alternative to titanium resisting corrosion and tarnishing, but it is cheap. The beryllium frame material is lightweight, strong, flexible and available in a wide range of colors. In addition, it is a good choice for those people with high skin acidity or those people who spend a large amount of time in or around salt water.
Besides the above plastic eyeglass frame materials and metal frame materials, there are some other frame materials available, such as aluminum, gold, silver or other biodegradables materials. You can choose the suitable one according to its performance, features, and price.
