Brýle

Brýle are a common optical device worn to correct vision or for protection. They typically consist of lenses, often made of glass or plastic, mounted in a frame that rests on the nose and over the ears. The primary function of corrective brýle is to adjust the focal length of the eye, allowing individuals with refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), or astigmatism to see clearly. The lenses are precisely shaped to bend light rays so they converge on the retina correctly.

Beyond vision correction, brýle serve other purposes. Sunglasses are designed with tinted lenses to reduce the intensity of sunlight and protect the eyes from harmful ultraviolet (UV) radiation. Safety brýle are used in various environments, such as construction sites or laboratories, to shield the eyes from physical hazards like flying debris or chemical splashes. Brýle can also be worn as a fashion accessory, with frames and lens designs chosen for aesthetic appeal. The materials used in brýle frames range from metal alloys to various plastics, and lens technology continues to evolve, offering features like anti-reflective coatings, scratch resistance, and photochromic properties that darken in sunlight.
