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.


Does it take time to adjust to progressive lenses?

How long should it take to get used to progressive lenses? I have never worn glasses before.Progressive lenses were developed to allow easy switching between near and far views. Progressive glasses are divided into four parts. The upper part is the far-light region. The lower part is the near-light region, and the middle part is a variable light region. From top to bottom, if the hyperopia film is gradually increased and the myopia film is gradually decreased. The middle variable area is on both sides of the astigmatism area. Because of the prism effect, when you see things, through this area, the object will be blurred, and the eyes will feel uncomfortable. If the height of the frame itself is very small, the transition zone of progressive multi-focus is very narrow, and the eyes may not adapt to the sunglasses. The current design of progressive lenses is still not mature. Imported brands are relatively stable but expensive, and domestic brands are not mature in design. For various reasons, progressive glasses may be difficult to adapt to wearing.



The Role of Fishing Sunglasses

The special effect of the polarized lens is to effectively eliminate and filter the scattered light from the beam. In general, a polarized lens can arrange all the light in the same direction, so that the visual field is clear and natural. It also blocks ultraviolet light, reducing damage to the eyes and clearing out blinding light. Fishing glasses have the function of polarized light, so they can block all harmful light without affecting the transmission of visible light, which can really achieve the function of eye protection. In addition to the basic anti-ultraviolet function, fishing glasses also have the functions of anti-glare, reducing pavement reflection light and water scale light, etc., suitable for driving, fishing, tourism, and daily wear.


About celluloid glasses

In 1929, the first large-scale production of sunglasses made of celluloid was made by SamFoster, an American who ran a women's accessories company facing bankruptcy and made it convenient to use the injection molding technology used to make hairbrushes. Sunglasses made of celluloid were sold on the beach of Grand West, New Jersey, and became very popular. Indeed, celluloid glasses were once popular because of their high-cost performance, but celluloid gradually faded out of people's eyes due to its poor chemical stability, flammability, and other shortcomings, with the emergence of new materials for glasses.

How to Test Computer Glasses (Clear Glasses)

First, we will show you how to test computer glasses with clear glasses.

1. Ask for Blue Light Glasses Brand Spectrum Report

To find out whether your blue light glasses are the best computer glasses, you should contact the company you bought them from and ask for a spectrum report. It will show you how much blue light your computer glasses can block.

After sending the spectrum report to you, you should make sure that your computer glasses are able to filter at least 30% blue light, otherwise, they are unsafe.

2. Use the Lens Reflection Test

As for how to test computer glasses, you can use the lens reflection test. You can see what color the light is that reflecting off the lenses.

If it reflects the blue light, they are filtering some blue light. If the reflection is violent or purple, the computer glasses may be not effective.

This is a good way for you to perform a blue light test at home.



What are NXT Lenses?

NXT lenses are made of Trivex materials. Trivex (Chinese name: Ethyl Carbamate Polymer) was invented by PPG in 2001.

Impact resistance:

Impact resistance is the main feature of the NXT lens. As a visual armor material originally used in the military field, Trivex has effective impact protection to the eye when it is most demanded. It is 10 times stronger than PC lenses in impact resistance and will last for life under normal use. It is the only explosion-proof safety lens on the market that can withstand external forces and turns.

Patented color injection technology :

Color representation is another important feature of NXT lenses. The biggest defect of the regular lens in dyeing is color aberration. The same color of the lens with different luminosity will produce different effects. The higher the refractive index, the serious the error. NXT lenses are a breakthrough in this respect. The patented color injection technology that infuses the color into the raw material gives the lens a natural color, ensuring that color aberrations are minimized and that they do not fade or change color over time or over long periods of use like other materials.

Abbe number and internal stress:

The Abbe number of NXT lenses made of Trivex is 43~45, which is close to CR39(58) and higher than PC lenses (29~32) and high folding lenses (32~41). At the same time, because the NXT lens is produced by the casting process, there is no stress in the finished lens, which further reduces the rainbow phenomenon, providing a guarantee for the clear visual effect and reducing eye fatigue.

Weight:

The specific gravity of NXT lens is 1.11g/cm3, 16% lighter than CR39 (1.32g/cm3) and 10% lighter than PC tablet (1.22g/cm3). The Trivex 1.53NXT medium-fold lens is so light that it can float.
