What do polarized glasses mean?

Most of the glasses we wear in our daily lives are polarized glasses, which are designed based on the principle of light polarization. They can effectively eliminate the glare caused by sunlight. They are especially important for drivers. They not only allow a wider field of vision while driving, but also bring a lot of fun to the journey. Polarized glasses have many uses, such as being worn when it rains, when fishing, etc.

Polarized lenses are made based on the principle of light polarization and have a unique function of eliminating glare first. They are particularly effective for drivers, improving vision and adding to the pleasure of riding.

2. The role of polarized glasses

1. The role of polarized sunglasses

Polarized sunglasses have the function of polarizing light, which can block all harmful light without affecting the transmission of visible light. They can effectively protect the eyes from harmful light in the sun.

Polarized lenses are made by pressing together multiple layers of thin resin materials. Each layer has different functions. The middle layer is the polarizing layer, which works like a Venetian blind and can filter out stray reflected light. The second and third layers can filter out 99.9% of harmful UV rays and reduce light intensity, and their functions are no different from those of ordinary sun lenses. The fourth and fifth layers of polarized lenses are impact-resistant layers, making the lenses less likely to break; the sixth and seventh layers are reinforced to make the lenses less likely to wear. Polarized lenses can filter out harmful light and protect your eyes.

3.1. When driving with polarized lenses, if you are driving in congested traffic, you will no longer be bothered by reflections from the sun and vehicles in front. It takes 1.5 seconds for the information seen by the eyes to be transmitted to the brain, and then the brain transmits instructions to the limbs. When the car is traveling at 100 kilometers per hour, 1.5 seconds means that the car has moved 40 meters from the time the driver sees the danger to the time he steps on the brakes. Due to the abnormal visual state, combined with the influence of many factors such as psychology, age, physical condition and driving environment, drivers often have various illusions while driving, which lead to incorrect operations and dangerous situations. Among these illusions, light illusions and color illusions are particularly obvious.

3.2. When fishing, use polarized lenses. The water waves sparkle under the sunlight, but you will not feel uncomfortable at all, but feel comfortable and free.

3.3. Use polarized lenses when skiing. You don’t have to worry about reflections and ultraviolet rays on the vast snowy fields, and you can glide as much as you want;

3.4. Use polarized lenses when it rains, and the traffic signs on the road covered by rainwater will appear clearly in front of you;

3.5. Use polarized lenses when on vacation to effectively block more ultraviolet rays, allowing you to fully enjoy your rare leisure time.
