Is It Worth Buying Polarized Sunglasses - KoalaEye

Is it worth buying polarized sunglasses?

In the previous article, we discussed “What are good affordable sunglasses brands?”. In this article, let’s talk about “Is it worth buying polarized sunglasses?”.

We know that when the sun shines on the road or water, reflected lights will irritate the eyes and makes the eyes feel dazzling and fatigued. The special effect of the polarized lens is to effectively eliminate and filter out the scattered light in the beam in order to make the visual field clear.

Features Of Polarized Sunglasses

Although polarized lenses can filter out a lot of irregular light interference and avoid glare, if the curvature of the lens itself cannot be in the optical standard refractive state, the polarizing effect will be weakened, affecting the authenticity of the image.(

The generally polarized sunglasses on the market are made of fiber sandwiched with a polarizing film. It is different from optical glass polarized sunglasses because of its soft texture and unstable arc. After the lens is fitted with the frame, the lens is difficult to reach the optical refractive standard, and the visual image is loose and deformed. Due to the instability of the arc, the lens is deformed, which directly leads to the poor clarity of the transparent image and the distortion of the image. All in all, the lens can not achieve the normal visual effect. Also, the surface of the lens is easy to scratch and wear and it is not durable.

Advantages Of Polarized Sunglasses

The reflected glare formed by sunlight on sand, water, snow, and road surfaces often causes eye discomfort and fatigue. The polarization angle and radian of polarized sunglasses are designed based on precise optical principles. This irregular reflected light can be effectively arranged and filtered. The light is arranged in the same direction and enters the eyes, making the surrounding scenery look soft and not dazzling.

How To Judge The Quality Of Polarized Sunglasses

1. It must be able to filter out more than 99% of ultraviolet rays in sunlight

2. It has the function of effectively blocking strong light.

3. The lens has a standard optical arc design to form an optical axis to produce a visual image.

4. The frame structure is firm and the frame material is excellent. The frame has an optical function design and it is comfortable and safe to wear.

The lens of Polarized sunglasses is an alloy layer material, generally composed of seven layers. The first and last layers are anti-wear. The second and sixth layers are UV protection. And the third and fifth layers are to filter harmful rays. So, the middle layer is the polarizing layer. The effect of UV protection for Polarized lenses is good, but they are not abrasion resistant and easy to scratch.

The polarizer can block the random reflection light, glare, and irregular reflection light of the object in the natural light. Compared with ordinary sunglasses, polarized sunglasses do not affect vision, and will not cause chromatic aberration. Long-term color contrast will affect people's perception of color. At the same time, it can effectively avoid the damage of ultraviolet rays to the eyes.
