During summer, many people choose to wear sunglass near me. When choosing sunglasses, don't just focus on whether their style is fashionable. The different categories of lenses cannot be ignored, as different types have different effects.

The term "polarized light" is often used in sunglasses near me, but many people do not understand its specific meaning. This type of lens is designed to filter out the dazzling light emitted by the sun in equal directions, and a special vertical coating is added to the lens. It is very suitable for outdoor activities such as sea activities, skiing, or fishing.

Another name for color-changing lenses is "photosensitive lenses". Originally transparent and colorless lenses, when exposed to strong light, will turn into colored lenses to protect the eyes. This is because silver halide chemicals are added to these types of lenses, which are suitable for both indoor and outdoor use.

Anti-reflective protective lenses can prevent strong light reflection, allowing you to see things undisturbed and clearer under strong light. The principle of this type of lens is very simple, which is to apply a layer of magnesium fluoride on the surface.

If you want to know if your sunglasses near me are equipped with anti-reflective protective lenses, you can aim your glasses at the light source. When you see purple or green reflections, it indicates that there is anti-reflective protective film on the lenses.

Color lenses, also known as "tinted lenses," use sunglasses that can absorb light of specific wavelengths. The principle behind this is to add some chemicals during the lens manufacturing process to make the lens appear colored. This type of lens is the most commonly used for sunglasses.
