| Sunglasses (also called sun spectacles) are a kind of visual correction aid, variously termed spectacles or glasses, which feature lenses that are coloured or darkened to screen out strong light from the eyes.
Many people find direct sunlight too bright to be comfortable, especially when reading from paper on which the sun directly shines. Also, with the rise of the atmosphere's damaged ozone layer, it has been recommended to the public to wear these kind of glasses on sunny days to protect the eyes from ultraviolet radiation, which can lead to the development of a cataract. Sunglasses have also been associated with film actors since the lighting involved in production is typically strong and uncomfortable to the naked eye. It is important to ensure that the makers of one's sunglasses ensure that the glasses protect against UV rays. Lenses that are simply dark but do not provide UV protection may actually make things worse, as the dimmer light causes the pupils to dilate, admitting more UV rays. Corrective lenses can be darkened to serve the same purpose, or secondary clip-on dark lenses can be placed in front of the regular lenses.
