Designer Sun Glasses For Boys



Designer Sun Glasses For Boys
Sun glasses are a form of protective eye wear designed primarily to prevent bright sun lightened high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are coloured, polarised or darkened. Health care professionals recommend eye protection whenever the sun comes out to protect the eyes from ultraviolet radiation (UV) and blue light, which can cause several serious eye problems. Sunglasses have long been associated with celebrities and film actors primarily from a desire to mask their identity. Sunglasses can improve visual comfort and visual clarity by protecting the eye from glare. There are three major sun glass standards, which are popularly known mostly as a reference for sun glass protection from UV radiation; the standards do, however, also include further requirements. Special protection is required for space travel because the sunlight is far more intense and harmful than on Earth, where it is always filtered through the atmosphere. Sun protection is needed against much higher UV radiation and even against harmful infrared radiation, both within and outside the spacecraft. Within the spacecraft, astronauts wear sunglasses with darker lenses and a thin protective gold coating. During space walks, the visor of the astronauts' helmets, which also has a thin gold coating for extra protection, functions as strong sunglasses.
