Napszemüveg

Napszemüveg is the Hungarian word for sunglasses. These are typically worn to protect the eyes from bright sunlight and high-energy visible light. They can also be worn for aesthetic purposes.

The primary function of napszemüveg is to prevent damage to the eyes from ultraviolet (UV) radiation. Prolonged exposure to UV rays can lead to serious eye conditions such as cataracts, macular degeneration, and photokeratitis (sunburn of the cornea). Quality napszemüveg will block 99% to 100% of UV-A and UV-B rays.

Beyond UV protection, napszemüveg also enhance visual comfort by reducing the intensity of bright light. This can make it easier to see in sunny conditions and reduce eye strain. Different lens tints can affect how colors are perceived and can be chosen based on specific activities or lighting conditions. For example, brown or grey tints are common for general use, while yellow or amber tints can improve contrast in overcast conditions.

The design and materials of napszemüveg vary widely. Frames can be made from plastic, metal, or more specialized materials. Lenses can be made from glass, polycarbonate, or other plastics, each offering different levels of impact resistance and optical clarity. Polarized lenses are an option that further reduces glare by filtering out horizontal light waves, which is particularly useful for activities like driving or being near water.
