How to choose fishing polarized sunglasses?

Anglers in the fishing process will focus on the water, the water in the sunlight reflected light will hurt the eyes, this time we need to choose a more comfortable to wear and does not damage the eye glasses, so how to choose glasses it? How to protect themselves against them?

The harmful effects of ultraviolet rays, can be said to be chronic killer eyes can cause eye keratitis, cataracts, macular degeneration and retinopathy and other eye problems. Sunglasses features are different, but only with anti-ultraviolet sunglasses can withstand while UVA and UVB rays, but a truly reliable sunglasses, must be able to block 99-100 percent of UVA rays. It should choose the lens of the eye may be snapping sunglasses - although sunglasses can provide 100 percent UV protection, but still fired into the eyes from the sun to go around the frame, it is best to choose to wear aviator sunglasses, the lens can be completely covered live on both sides of the face, so sunlight can get into seamless. General sunglasses as no anti-UVA/UVB ultraviolet ensure the eyes may cause more damage. The reason is that the lens will make dark eye pupil dilation, but allow more UVA rays have the opportunity to enter the eye, the retina and causing greater damage to the lens.  

In addition to receiving direct light, it will also receive interference from all sides because of light reflection and refraction. Glare can interfere with a variety of real vision. Polarized lenses are currently the only commercially available product resolves all glare lenses (including reflective glare). What is glare, when a high-intensity light source, or the brightness of the background with the center of the field will produce large difference in glare. When the eye receives glare, ranging from disturbances of sight, while resulting in temporary blindness, dangerous.

Glare is divided into four categories：

(Distracting Glare)
Distracting Glare caused mainly reflecting lens, such as street lights, night time lights and so on. Interfering glare disrupt our line of sight, people have to squint, and likely to cause eye fatigue TB.

(Discomforting Glare)
Discomfort glare refers to the discomfort that is very light, which may be direct or reflected light, even on cloudy days, sunny situation, or when switching between different luminosity environments (such as just out from inside a tunnel) may occur . Discomfort glare of people must squinting, blocking the light.

(Disabling Glare)
Disabling Glare from strong light sources, such as car headlights look. Incapacitating glare will be reduced depending on the degree of vision and clear, and the ability to react with the image contrast. In addition to eye fatigue, but sometimes even cause temporary visual impairment.

(Blinding Glare)
Blinding Glare is a shiny reflection from the surface of the material, such as water, roads, snow, etc., can cause temporary blindness. Temporarily blinding glare of the most dangerous glare, because often occurs when driving or skiing. Such reflective glare polarized light, the need to rely on polarized lenses filter out.

Fishing glasses can eliminate water scales, so anglers can see fish bait; to increase color saturation and polarized sunglasses to prevent eye fatigue; fishing glasses should be worn greenish gray or gray lens is better, and the lens has a polarizing function, UV400 polarized sunglasses and other proper function.

Fishing glasses not only for fishing, but it has the function, but also in driving, playing golf, traveling, everyday wear. Anglers should avoid wearing glasses and easy oxidation and corrosion, wear resistant to oxidation and corrosion of glasses plate frames, aluminum-magnesium alloy, titanium and titanium alloy.
