WHAT KIND OF PROTECTION DO KOH LENSES HAVE?

KOH lenses are 100% Sun Protection UV400 CE, they are made of a resistant and light plastic material called polycarbonate.

These lenses have several prominent features:

RESISTANCE: Polycarbonate is a highly impact resistant material, which makes it ideal for sports glasses. They are harder to break compared to regular glass or plastic lenses, making them more durable and safer.
LIGHTWEIGHT: Polycarbonate lenses are considerably lighter than glass lenses, making them more comfortable to wear for long periods of time. This is especially beneficial for those who wear glasses. of sun for the whole day.
UV400 PROTECTION: Sunglasses with UV400 protection block 99-100% of ultraviolet light. They filter and block light rays with wavelengths up to 400 nanometers, including UVA and UVB rays.

As for the KOH lenses, some of them are also polarized and/or have a Revo filter:

POLARIZED LENSES: Polarized lenses are designed to reduce glare caused by reflected light from flat surfaces, such as water, snow, or roads. These lenses have a special filter that blocks polarized light at certain angles, improving visual clarity and reducing eye fatigue.
REVO: The Revo filter is a multi-layer NASA technology-based coating applied to lenses to improve vision clarity and contrast. This coating reduces reflections and improves color perception, providing a sharper, more vivid viewing experience.

In short, polycarbonate lenses are strong, lightweight, and offer UV400 protection. KOH lenses may have additional features, such as being polarized to reduce glare and having a Revo filter to improve visual clarity and contrast. These additional features can provide a higher quality and more comfortable viewing experience.

WHAT IS THE MATERIAL OF MANUFACTURING THE FRAMES OF THE KOH SUNGLASSES?

KOH sunglasses frames are made from several different materials.

PC (Polycarbonate): Polycarbonate is a strong, lightweight plastic that is widely used in the manufacture of eyeglass frames. Offers durability and impact resistance.
TR90: TR90 is a type of thermoplastic polymer material that is also lightweight and strong. It has excellent flexibility and shape memory, which means that it can return to its original shape after being deformed.
Metal: Metal frames, such as stainless steel or titanium, are popular for their durability and sleek looks. Additionally, metal can be molded into a variety of styles and designs.
