Polarized light may be the most important element in any pair of sunglasses. Polarized lenses reduce glare from water, glass, or other reflections, making fishermen, drivers, hikers, or anyone outside can see more clearly and more comfortably.
Polarized lenses can also protect your eyes and skin from UV rays, which can damage your retina over time. Many people consider polarized lenses as an essential feature when buying sunglasses. You will find that there are a variety of lens colors and types to suit certain situations.
Can you get clear polarized glasses?
For now, you will not be able to buy clear polarized sunglasses anywhere on the market. To achieve polarization, your glasses must have at least some shades. This is due to the working principle of polarization. However, if you want to buy clear polarized glasses for fishing, you can try to buy lightly tinted polarized sunglasses.
Compared with darker-toned lenses, shades of green, yellow, and amber provide more light transmittance. The color of the lens helps increase contrast and block blue light, thereby counteracting the effects of glare. Therefore, you will get the benefits of polarized lenses while getting more light. Polarized lenses with only slight shades of yellow, green, or amber may be your best choice. Choose yellow polarized sunglasses for fishing, so you can easily find fish and habitat in the water.
The working principle of polarization
When manufacturing lenses, chemicals are applied to glass or plastic lenses to make them polarized. This chemical is placed on the lens in a vertical direction, blocking horizontal light from glare and reflections. This polarization will darken your vision, but it tends to eliminate glare, reduce eye strain, prevent UV exposure, and make contrast easier to see.
This laminate layer is usually applied to the surface of cheaper sunglasses to eliminate polarization. More expensive lenses will apply polarization between the lens layers. This usually allows them to last longer and be more durable.
The tint of polarized lenses
The lenses of polarized sunglasses have specific colors and shades. This tint helps these sunglasses do their job effectively. It helps filter the sunlight reflected from the water surface. These sunglasses are available in a variety of shades and qualities, and each shade has a different purpose, although the main job of all lenses is to help you see more clearly by enhancing contrast and increasing the clarity of objects.
You can choose a variety of types of polarized lenses, from light shades such as amber and brown to dark shades such as gray and blue. However, if you are looking for transparent polarized glasses, you should know that they are not yet available. Since the main purpose of polarized sunglasses is to reduce brightness and glare, transparent lenses cannot block light from specific directions. This is because the iodine crystals in the lens are arranged horizontally. If the lens is not plated with iodine crystals, the polarizing effect of sunglasses will be reduced, which is the basic work of polarized lenses. Therefore, it is impossible to manufacture polarized lenses with no tint.
Even the lightest colored polarized lenses will have a 20% to 30% tint. Although clear lenses will increase the amount of light transmitted and help you see more clearly, they will be similar to your simple glasses without staining, because there will be no polarization effect. The color tone of polarized lenses helps filter out the brightness that can cause eye strain and fatigue. Therefore, the darker the lens, the better they block sunlight.
