Päikeseprilliklaas

Päikeseprilliklaas refers to the lenses used in sunglasses. These lenses are designed to protect the wearer's eyes from bright sunlight and harmful ultraviolet (UV) radiation. They achieve this by reducing the amount of visible light that passes through them and by filtering out UV rays.

There are various types of päikeseprilliklaas, each offering different properties. One common type is tinted päikeseprilliklaas, where the lens material is colored. The tint can vary in color and intensity, affecting how much light is transmitted and how colors are perceived. Darker tints reduce brightness more significantly. Polarized päikeseprilliklaas are another important category. These lenses have a special filter that blocks reflected glare from surfaces like water, snow, and roads, significantly improving visual clarity and reducing eye strain.

Päikeseprilliklaas can also have various coatings. Anti-reflective coatings can be applied to the back surface to reduce reflections from behind. Scratch-resistant coatings help to prevent minor abrasions. Many päikeseprilliklaas also incorporate UV protection, often specified as UV400, meaning they block light wavelengths up to 400 nanometers, which includes all harmful UVA and UVB rays. The material of the päikeseprilliklaas can range from glass to various types of plastic, each with its own advantages regarding durability, weight, and optical clarity.
