Gray Lenses: Gray lenses absorb all colors of light evenly, so objects appear darker without noticeable color distortion, providing a natural and realistic look. They belong to the neutral color family.
Brown Lenses: These filters out a significant amount of blue light, improving visual contrast and clarity. They are particularly effective in heavily polluted or foggy conditions. They generally block reflected light from smooth, shiny surfaces, allowing the wearer to still see fine details, making them ideal for drivers.
Green Lenses: While absorbing light, they maximize the amount of green light reaching the eyes, providing a cool and comfortable feeling, suitable for those prone to eye fatigue.
Blue-Gray Lenses: Similar to gray lenses, they are neutral lenses, but darker and have a higher visible light absorption rate.
Mercury Lenses: These lenses have a high-density mirror coating. They absorb and reflect more visible light, making them suitable for outdoor sports enthusiasts.
Yellow lenses: Strictly speaking, these lenses are not sunglasses because they hardly reduce visible light. However, in foggy or twilight conditions, yellow lenses can improve contrast and provide more accurate vision, hence they are also called night vision glasses. Some young people wear yellow-lensed "sunglasses" as a fashion statement.
Light blue, light pink, etc. lenses: These are also more decorative than practical.
Dark green lenses: These absorb heat and provide a cooling sensation.
Blue lenses: Suitable for beach outings, blue sunglasses effectively filter out the light blue reflections from the sea and sky.
