5 In 1 Clip On Sunglasses Polarized Magnetic Night And Day Driving Glasses

Sunglasses, also known as sunshades, are used for shading. People usually need to adjust their pupil size to adjust their light flux when exposed to sunlight. When the intensity of light exceeds the human eye's ability to adjust, it can cause harm to the eyes.
Lens classification
The types of sunglasses lenses are roughly divided into five types: anti reflective protective lenses, colored lenses, coated lenses, polarized lenses, and color changing lenses.
1. Anti reflective protective lenses: This type of lens is coated with a thin layer of magnesium fluoride on the surface to prevent strong light reflection, making things clearer and less affected by strong light interference. To check if your sunglasses really use anti reflective protective lenses, you can aim your glasses at the light source. If you see purple or green reflections, it means that the lenses are indeed coated with anti reflective protective film.
2. Colored lenses: also known as "dyed lenses", refer to the process of adding some chemicals to the lens to present color and absorb specific wavelengths of light during the lens manufacturing process. This is the most commonly used type of lens for sunglasses.
3. Colored lenses: This type of lens presents the same effect as colored lenses, but is made in a different way. It applies color to the surface of the lens, and is most commonly known as the "gradient colored lens". The color is the darkest on top and then gradually lighter down. Generally, sunglasses with a certain degree are processed by coloring the lenses.
4. Polarizing lenses: In order to filter out the dazzling light from the sun in equal directions on water, land, or snow, a special vertical coating is added to the lens, which is called a polarizing lens. Most suitable for outdoor activities such as sea activities, skiing, or fishing.
5. Color changing lenses: also known as "photosensitive lenses". Because silver halide chemicals are added to the lenses, the originally transparent and colorless lenses will turn into colored lenses when exposed to strong light for protection, making them suitable for both indoor and outdoor use.
6. Sunglass clip: Sunglass clip is a polarized sunglasses designed specifically for people with myopia, effectively preventing glare and UV rays. Especially suitable for outdoor sports such as driving, outdoor activities, and fishing. By using polarizing lens technology, the visual resolution is greatly improved. Eliminate 99% of reflected and scattered light, making your field of vision clearer and smoother. The lens is specially reinforced with film, which effectively enhances wear resistance, scratch resistance, and impact resistance.
7. Night driving lenses: Night driving lenses should be able to block more than 80% of the opponent's car's strong light, and the main lens transmittance must be>75%. Observing the road is not affected, and wearing a good set of driving night mirrors at night can not only help drivers see the road surface clearly, but also effectively reduce the glare and other harmful light emitted by the opponent's car headlights. While blocking strong light, they can also see the road surface clearly, So as to ensure your driving safety.
