Aluminum Night Driving Glasses

These night vision glasses feature advanced HD technology. The aluminum frame is lightweight, allowing you to comfortably wear your driving glasses and reduce glare for safe driving. Because the lenses are yellow, these glasses act as night vision goggles to reduce glare, reflections, and their negative effects, while improving and brightening the visual area. Polarized lenses have a special anti-reflective coating that eliminates intense reflected light and reduces glare and scattered reflections. They can double as day and night glasses, improving clarity around the clock.

The arm length is an important part of the size of the glasses.

Spectacle frames are standard optical products. Just like people's clothes and shoes, they all have their own size. Usually, specs for the size of the glasses are on the inside of the temple, on the bridge of the nose, or on the label. In general, the frames of the glasses are marked with the width of the frames, the width of the bridge of the nose, and the length of the arm. For example, the inner side of the temple is labeled: 52口 18-135, indicating the lens width of 52mm, the width of the nose bridge of 18mm, and the arm length is 135mm.



Why do glasses with the same prescription feel different?

The old glasses 'remodeled' your eyes. Sometimes, all data on optometry and processing are accurate, and the spectacles equipped are in full compliance with the prescription for optometry, or the power of new spectacles is exactly the same as that of the old spectacles, but you will still be dizzy when wearing the new spectacles. This is because the old glasses 'remodeled' their eyes during long-term wear. For example, the old glasses used by some people have been severely deformed. The temples are no longer in the same plane, and the optical center area of the lens will deviate from the interpupillary distance measured by the glasses at that time. However, the wearer does not mention this situation, and the eyes gradually adapt to this kind of deviation. After putting on a new pair of glasses, you will not adapt to them.


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.
