Fishing polarized glasses are actually a kind of polarized sunglasses, which can effectively eliminate and filter the scattered light in the beam, so that the light can enter the visual image of the eyes on the transmission axis on the right track. Generally speaking, polarized glasses can organize all the light into In the same direction, the vision is clear and natural.

1. The main functions of fishing glasses in fishing are as follows:

Block ultraviolet rays that damage fishermen's eyes and even skin, and reduce light damage to eyes. It can increase the color contrast, and it will increase the perspective when looking at red light and green light. Because the floats basically have red and green colors, it will be more clear when we look at the floats. Eliminate glare (such as the reflection of scales on the water surface and the drift cannot be seen clearly). It has the effect of filling light on cloudy days. Protective effect on the eyes, such as wind and so on. Relieves eye fatigue. When fishing in calm water, the light is originally facing us directly. Because of the wind and waves on the water, there will be countless reflective surfaces, just like we are facing countless mirrors, so we can’t see the float clearly. After a long time Eyes can be very tired. By filtering out these glare can play a role in reducing visual fatigue.

2. Classification of fishing glasses

According to the wearing method, fishing glasses can be divided into general fishing glasses and clip-on fishing glasses. The clip-on fishing glasses are mainly developed for wearing myopia glasses. As long as you gently clip on the myopia glasses, you can clip the fishing lenses on them to achieve a polarizing effect. According to the color of the lens, there are more points. Generally speaking, it can be divided into dark color, light color (bright color) and photochromic mirror. Dark colors such as black, gray, green, red, bronze and so on. Light colors mainly refer to yellow, light red, light copper, light green and other colors. Darkening lenses absorb light and darken it when exposed to light, then automatically fade and restore vision when the light stops. Photochromic lenses are made by adding silver halide as a sensitizer to lenses made of special materials, and a small amount of copper ions as a sensitizer. After treatment at a high temperature of 500 ° C, the silver halide is agglomerated into microcrystals of a certain size. Under the irradiation of ultraviolet light or short-wave visible light, silver halide will decompose into colloidal silver particles, causing the glass to change color. After the light stops, the silver atoms and the halogen recombine, and the lens will fade. According to the material, there are three types of lenses: glass material, resin material, and TAC material.
