Are polarized glasses good for fishing?
Fishing goggles are polarized lenses. Fishing goggles are a type of goggles that can remove scales on the surface of the water so that the fisherman can see the fish taking the bait. Polarized sunglasses increase color saturation and prevent eye strain. Wear gray glasses on sunny days when fishing. They can fully absorb infrared rays, as well as most ultraviolet rays, without changing the original color of the scene. Warm, natural colors are a popular lens choice. Wear green glasses on cloudy days when fishing. like gray glasses, they can absorb all the lone infrared rays and 99% of the ultraviolet rays, but sometimes the color of the scene after passing through the green lens will be changed. But because green brings a cool and refreshing feeling, it is also good for eye protection.
How to Find Reading Glasses Strengths?
Some reading glasses also come with strengths. So, how do you know what strength reading glasses to get and how to find reading glasses strengths? The strength of all reading glasses is measured in dioptre, with units increasing by 0.25 dioptre depending on the power of the lens.
The reading glasses strengths range from +0.75 dioptre to +3.00 dioptre. Both lenses have the same power which is indicated by a permanent marking on the inside of the frame or with a removable sticker on the lens. So, you can find the reading glasses strengths of the glasses.
The important thing you need to notice is that when higher the number, the greater the power of the lenses is when choosing reading glasses. So, glasses with a marking of 1.0 are low power while those marking +3.0 are high powered.
How to Choose Reading Glasses?
If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.
However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.
In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.

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.
